Red Hat Security Advisory
Synopsis: Updated Perl packages fix security issues
Advisory ID: RHSA-2005:105-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2005-105.html
Issue date: 2005-02-07
Updated on: 2005-02-07
Product: Red Hat Enterprise Linux
CVE Names: CAN-2005-0155 CAN-2005-0156
- - ---------------------------------------------------------------------
1. Summary:
Updated Perl packages that fix several security issues are now available
for Red Hat Enterprise Linux 3.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, ppc64, 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. Problem description:
Perl is a high-level programming language commonly used for system
administration utilities and Web programming.
Kevin Finisterre discovered a stack based buffer overflow flaw in sperl,
the Perl setuid wrapper. A local user could create a sperl executable
script with a carefully created path name, overflowing the buffer and
leading to root privilege escalation. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2005-0156 to
this issue.
Kevin Finisterre discovered a flaw in sperl which can cause debugging
information to be logged to arbitrary files. By setting an environment
variable, a local user could cause sperl to create, as root, files with
arbitrary filenames, or append the debugging information to existing files.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2005-0155 to this issue.
Users of Perl are advised to upgrade to these updated packages, which
contain backported patches to correct these issues.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied. Use Red Hat
Network to download and update your packages. To launch the Red Hat
Update Agent, use the following command:
up2date
For information on how to install packages manually, refer to the
following Web page for the System Administration or Customization
guide specific to your system:
http://www.redhat.com/docs/manuals/enterprise/
5. Bug IDs fixed (http://bugzilla.redhat.com/):
146737 - CAN-2005-0155 multiple setuid perl issues (CAN-2005-0156)
140227 - Potential insecurity in CGI.pm
