Red Hat Security Advisory
Synopsis: Critical: nspr and nss security, bug fix, and enhancement update
Advisory ID: RHSA-2009:1186-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-1186.html
Issue date: 2009-07-30
CVE Names: CVE-2009-2404 CVE-2009-2408 CVE-2009-2409
=====================================================================
1. Summary:
Updated nspr and nss packages that fix security issues, bugs, and add an
enhancement are now available for Red Hat Enterprise Linux 5.
This update has been rated as having critical security impact by the Red
Hat Security Response Team.
The packages with this update are identical to the packages released by
RHBA-2009:1161 on the 20th of July 2009. They are being reissued as a Red
Hat Security Advisory as they fixed a number of security issues that were
made public today. If you are installing these packages for the first time,
they also provide a number of bug fixes and add an enhancement, as detailed
in RHBA-2009:1161. Since the packages are identical, there is no need to
install this update if RHBA-2009:1161 has already been installed.
2. Relevant releases/architectures:
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
3. Description:
Netscape Portable Runtime (NSPR) provides platform independence for non-GUI
operating system facilities. These facilities include threads, thread
synchronization, normal file and network I/O, interval timing, calendar
time, basic memory management (malloc and free), and shared library linking.
Network Security Services (NSS) is a set of libraries designed to support
the cross-platform development of security-enabled client and server
applications. Applications built with NSS can support SSLv2, SSLv3, TLS,
and other security standards.
These updated packages upgrade NSS from the previous version, 3.12.2, to a
prerelease of version 3.12.4. The version of NSPR has also been upgraded
from 4.7.3 to 4.7.4.
Moxie Marlinspike reported a heap overflow flaw in a regular expression
parser in the NSS library used by browsers such as Mozilla Firefox to match
common names in certificates. A malicious website could present a
carefully-crafted certificate in such a way as to trigger the heap
overflow, leading to a crash or, possibly, arbitrary code execution with
the permissions of the user running the browser. (CVE-2009-2404)
Note: in order to exploit this issue without further user interaction in
Firefox, the carefully-crafted certificate would need to be signed by a
Certificate Authority trusted by Firefox, otherwise Firefox presents the
victim with a warning that the certificate is untrusted. Only if the user
then accepts the certificate will the overflow take place.
Dan Kaminsky discovered flaws in the way browsers such as Firefox handle
NULL characters in a certificate. If an attacker is able to get a
carefully-crafted certificate signed by a Certificate Authority trusted by
Firefox, the attacker could use the certificate during a man-in-the-middle
attack and potentially confuse Firefox into accepting it by mistake.
(CVE-2009-2408)
Dan Kaminsky found that browsers still accept certificates with MD2 hash
signatures, even though MD2 is no longer considered a cryptographically
strong algorithm. This could make it easier for an attacker to create a
malicious certificate that would be treated as trusted by a browser. NSS
now disables the use of MD2 and MD4 algorithms inside signatures by
default. (CVE-2009-2409)
All users of nspr and nss are advised to upgrade to these updated packages,
which resolve these issues and add an enhancement.

1. Summary:
Updated nspr and nss packages that fix security issues and a bug are now
available for Red Hat Enterprise Linux 4.
This update has been rated as having critical security impact by the Red
Hat Security Response Team.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64
3. Description:
Netscape Portable Runtime (NSPR) provides platform independence for non-GUI
operating system facilities. These facilities include threads, thread
synchronization, normal file and network I/O, interval timing, calendar
time, basic memory management (malloc and free), and shared library linking.
Network Security Services (NSS) is a set of libraries designed to support
the cross-platform development of security-enabled client and server
applications. Applications built with NSS can support SSLv2, SSLv3, TLS,
and other security standards.
These updated packages upgrade NSS from the previous version, 3.12.2, to a
prerelease of version 3.12.4. The version of NSPR has also been upgraded
from 4.7.3 to 4.7.4.
Moxie Marlinspike reported a heap overflow flaw in a regular expression
parser in the NSS library used by browsers such as Mozilla Firefox to match
common names in certificates. A malicious website could present a
carefully-crafted certificate in such a way as to trigger the heap
overflow, leading to a crash or, possibly, arbitrary code execution with
the permissions of the user running the browser. (CVE-2009-2404)
Note: in order to exploit this issue without further user interaction in
Firefox, the carefully-crafted certificate would need to be signed by a
Certificate Authority trusted by Firefox, otherwise Firefox presents the
victim with a warning that the certificate is untrusted. Only if the user
then accepts the certificate will the overflow take place.
Dan Kaminsky discovered flaws in the way browsers such as Firefox handle
NULL characters in a certificate. If an attacker is able to get a
carefully-crafted certificate signed by a Certificate Authority trusted by
Firefox, the attacker could use the certificate during a man-in-the-middle
attack and potentially confuse Firefox into accepting it by mistake.
(CVE-2009-2408)
Dan Kaminsky found that browsers still accept certificates with MD2 hash
signatures, even though MD2 is no longer considered a cryptographically
strong algorithm. This could make it easier for an attacker to create a
malicious certificate that would be treated as trusted by a browser. NSS
now disables the use of MD2 and MD4 algorithms inside signatures by
default. (CVE-2009-2409)
These version upgrades also provide a fix for the following bug:
* SSL client authentication failed against an Apache server when it was
using the mod_nss module and configured for NSSOCSP. On the client side,
the user agent received an error message that referenced "Error Code:
- - -12271" and stated that establishing an encrypted connection had failed
because the certificate had been rejected by the host.
On the server side, the nss_error_log under /var/log/httpd/ contained the
following message:
[error] Re-negotiation handshake failed: Not accepted by client!?
Also, /var/log/httpd/error_log contained this error:
SSL Library Error: -8071 The OCSP server experienced an internal error
With these updated packages, the dependency problem which caused this
failure has been resolved so that SSL client authentication with an
Apache web server using mod_nss which is configured for NSSOCSP succeeds
as expected. Note that if the presented client certificate is expired,
then access is denied, the user agent is presented with an error message
about the invalid certificate, and the OCSP queries are seen in the OCSP
responder. Also, similar OCSP status verification happens for SSL server
certificates used in Apache upon instance start or restart. (BZ#508027)
All users of nspr and nss are advised to upgrade to these updated packages,
which resolve these issues.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

Red Hat Security Advisory
Synopsis: Critical: seamonkey security update
Advisory ID: RHSA-2009:1185-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-1185.html
Issue date: 2009-07-30
CVE Names: CVE-2009-2404
=====================================================================
1. Summary:
Updated seamonkey packages that fix a security issue are now available for
Red Hat Enterprise Linux 3.
This update has been rated as having critical security impact by the Red
Hat Security Response Team.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64
3. Description:
SeaMonkey is an open source Web browser, email and newsgroup client, IRC
chat client, and HTML editor.
Moxie Marlinspike reported a heap overflow flaw in a regular expression
parser in the NSS library (provided by SeaMonkey) used to match common
names in certificates. A malicious website could present a
carefully-crafted certificate in such a way as to trigger the heap
overflow, leading to a crash or, possibly, arbitrary code execution with
the permissions of the user running SeaMonkey. (CVE-2009-2404)
Note: in order to exploit this issue without further user interaction, the
carefully-crafted certificate would need to be signed by a Certificate
Authority trusted by SeaMonkey, otherwise SeaMonkey presents the victim
with a warning that the certificate is untrusted. Only if the user then
accepts the certificate will the overflow take place.
All SeaMonkey users should upgrade to these updated packages, which contain
a backported patch to correct this issue. After installing the updated
packages, SeaMonkey must be restarted for the update to take effect.
4. Solution:
Before applying this update, make sure that all previously-released

Red Hat Security Advisory
Synopsis: Critical: nspr and nss security and bug fix update
Advisory ID: RHSA-2009:1190-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-1190.html
Issue date: 2009-07-31
CVE Names: CVE-2009-2404 CVE-2009-2408 CVE-2009-2409
=====================================================================
1. Summary:
Updated nspr and nss packages that fix security issues and bugs are now
available for Red Hat Enterprise Linux 4.7 Extended Update Support.
This update has been rated as having critical security impact by the Red
Hat Security Response Team.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS version 4.7.z - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux ES version 4.7.z - i386, ia64, x86_64
3. Description:
Netscape Portable Runtime (NSPR) provides platform independence for non-GUI
operating system facilities. These facilities include threads, thread
synchronization, normal file and network I/O, interval timing, calendar
time, basic memory management (malloc and free), and shared library linking.
Network Security Services (NSS) is a set of libraries designed to support
the cross-platform development of security-enabled client and server
applications. Applications built with NSS can support SSLv2, SSLv3, TLS,
and other security standards.
These updated packages upgrade NSS from the previous version, 3.12.2, to a
prerelease of version 3.12.4. The version of NSPR has also been upgraded
from 4.7.3 to 4.7.4.
Moxie Marlinspike reported a heap overflow flaw in a regular expression
parser in the NSS library used by browsers such as Mozilla Firefox to match
common names in certificates. A malicious website could present a
carefully-crafted certificate in such a way as to trigger the heap
overflow, leading to a crash or, possibly, arbitrary code execution with
the permissions of the user running the browser. (CVE-2009-2404)
Note: in order to exploit this issue without further user interaction in
Firefox, the carefully-crafted certificate would need to be signed by a
Certificate Authority trusted by Firefox, otherwise Firefox presents the
victim with a warning that the certificate is untrusted. Only if the user
then accepts the certificate will the overflow take place.
Dan Kaminsky discovered flaws in the way browsers such as Firefox handle
NULL characters in a certificate. If an attacker is able to get a
carefully-crafted certificate signed by a Certificate Authority trusted by
Firefox, the attacker could use the certificate during a man-in-the-middle
attack and potentially confuse Firefox into accepting it by mistake.
(CVE-2009-2408)
Dan Kaminsky found that browsers still accept certificates with MD2 hash
signatures, even though MD2 is no longer considered a cryptographically
strong algorithm. This could make it easier for an attacker to create a
malicious certificate that would be treated as trusted by a browser. NSS
now disables the use of MD2 and MD4 algorithms inside signatures by
default. (CVE-2009-2409)
These version upgrades also provide fixes for the following bugs:
* SSL client authentication failed against an Apache server when it was
using the mod_nss module and configured for NSSOCSP. On the client side,
the user agent received an error message that referenced "Error Code:
- - -12271" and stated that establishing an encrypted connection had failed
because the certificate had been rejected by the host.
On the server side, the nss_error_log under /var/log/httpd/ contained the
following message:
[error] Re-negotiation handshake failed: Not accepted by client!?
Also, /var/log/httpd/error_log contained this error:
SSL Library Error: -8071 The OCSP server experienced an internal error
With these updated packages, the dependency problem which caused this
failure has been resolved so that SSL client authentication with an
Apache web server using mod_nss which is configured for NSSOCSP succeeds
as expected. Note that if the presented client certificate is expired,
then access is denied, the user agent is presented with an error message
about the invalid certificate, and the OCSP queries are seen in the OCSP
responder. Also, similar OCSP status verification happens for SSL server
certificates used in Apache upon instance start or restart. (BZ#508026)
* NSS uses a software integrity test to detect code corruption. RPM
transactions and system link optimization daemons (such as prelink) can
change the contents of libraries, causing the software integrity test to
fail. In combination with the updated prelink package (RHBA-2009:1041),
these updated packages can now prevent software integrity test failures.
(BZ#495938)
All users of nspr and nss are advised to upgrade to these updated packages,
which resolve these issues.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at
