IBM MQ for HP NonStop Server is affected by OpenSSL vulnerability CVE-2019-1552
Security Bulletin
Summary
IBM MQ for HP NonStop Server is affected by OpenSSL vulnerability CVE-2019-1552
Vulnerability Details
CVEID: CVE-2019-1552
DESCRIPTION: OpenSSL has internal defaults for a directory tree where it can
find a configuration file as well as certificates used for verification in TLS.
This directory is most commonly referred to as OPENSSLDIR, and is configurable
with the --prefix / --openssldir configuration options. For OpenSSL versions
1.1.0 and 1.1.1, the mingw configuration targets assume that resulting programs
and libraries are installed in a Unix-like environment and the default prefix
for program installation as well as for OPENSSLDIR should be '/usr/local'.
However, mingw programs are Windows programs, and as such, find themselves
looking at sub-directories of 'C:/usr/local', which may be world writable,
which enables untrusted users to modify OpenSSL's default configuration, insert
CA certificates, modify (or even replace) existing engine modules, etc. For
OpenSSL 1.0.2, '/usr/local/ssl' is used as default for OPENSSLDIR on all Unix
and Windows targets, including Visual C builds. However, some build
instructions for the diverse Windows targets on 1.0.2 encourage you to specify
your own --prefix. OpenSSL versions 1.1.1, 1.1.0 and 1.0.2 are affected by this
issue. Due to the limited scope of affected deployments this has been assessed
as low severity and therefore we are not creating new releases at this time.
Fixed in OpenSSL 1.1.1d (Affected 1.1.1-1.1.1c). Fixed in OpenSSL 1.1.0l
(Affected 1.1.0-1.1.0k). Fixed in OpenSSL 1.0.2t (Affected 1.0.2-1.0.2s).

IBM MQ for HP NonStop Server is affected by multiple OpenSSL vulnerabilities
(CVE-2019-1547,CVE-2019-1549, CVE-2019-1563)
Security Bulletin
Summary
IBM MQ for HP NonStop Server is affected by multiple OpenSSL vulnerabilities
CVE-2019-1547, CVE-2019-1549 and CVE-2019-1563
Vulnerability Details
CVEID: CVE-2019-1547
DESCRIPTION: Normally in OpenSSL EC groups always have a co-factor present and
this is used in side channel resistant code paths. However, in some cases, it
is possible to construct a group using explicit parameters (instead of using a
named curve). In those cases it is possible that such a group does not have the
cofactor present. This can occur even where all the parameters match a known
named curve. If such a curve is used then OpenSSL falls back to non-side
channel resistant code paths which may result in full key recovery during an
ECDSA signature operation. In order to be vulnerable an attacker would have to
have the ability to time the creation of a large number of signatures where
explicit parameters with no co-factor present are in use by an application
using libcrypto. For the avoidance of doubt libssl is not vulnerable because
explicit parameters are never used. Fixed in OpenSSL 1.1.1d (Affected
1.1.1-1.1.1c). Fixed in OpenSSL 1.1.0l (Affected 1.1.0-1.1.0k). Fixed in
OpenSSL 1.0.2t (Affected 1.0.2-1.0.2s).
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
167020 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N)
CVEID: CVE-2019-1549
DESCRIPTION: OpenSSL 1.1.1 introduced a rewritten random number generator
(RNG). This was intended to include protection in the event of a fork() system
call in order to ensure that the parent and child processes did not share the
same RNG state. However this protection was not being used in the default case.
A partial mitigation for this issue is that the output from a high precision
timer is mixed into the RNG state so the likelihood of a parent and child
process sharing state is significantly reduced. If an application already calls
OPENSSL_init_crypto() explicitly using OPENSSL_INIT_ATFORK then this problem
does not occur at all. Fixed in OpenSSL 1.1.1d (Affected 1.1.1-1.1.1c).
CVSS Base score: 3.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
167021 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2019-1563
DESCRIPTION: In situations where an attacker receives automated notification of
the success or failure of a decryption attempt an attacker, after sending a
very large number of messages to be decrypted, can recover a CMS/PKCS7
transported encryption key or decrypt any RSA encrypted message that was
encrypted with the public RSA key, using a Bleichenbacher padding oracle
attack. Applications are not affected if they use a certificate together with
the private RSA key to the CMS_decrypt or PKCS7_decrypt functions to select the
correct recipient info to decrypt. Fixed in OpenSSL 1.1.1d (Affected
1.1.1-1.1.1c). Fixed in OpenSSL 1.1.0l (Affected 1.1.0-1.1.0k). Fixed in
OpenSSL 1.0.2t (Affected 1.0.2-1.0.2s).
CVSS Base score: 3.7
