===================================================================== Red Hat Security Advisory
Synopsis: Moderate: glib2 security update Advisory ID: RHSA-2009:0336-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-0336.html Issue date: 2009-03-24 CVE Names: CVE-2008-4316 =====================================================================
1. Summary:
Updated glib2 packages that fix several security issues are now available for Red Hat Enterprise Linux 5.
This update has been rated as having moderate security impact by the Red Hat Security Response Team.
2. Relevant releases/architectures:
RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
3. Description:
GLib is the low-level core library that forms the basis for projects such as GTK+ and GNOME. It provides data structure handling for C, portability wrappers, and interfaces for such runtime functionality as an event loop, threads, dynamic loading, and an object system.
Diego Pettenò discovered multiple integer overflows causing heap-based buffer overflows in GLib's Base64 encoding and decoding functions. An attacker could use these flaws to crash an application using GLib's Base64 functions to encode or decode large, untrusted inputs, or, possibly, execute arbitrary code as the user running the application. (CVE-2008-4316)
Note: No application shipped with Red Hat Enterprise Linux 5 uses the affected functions. Third-party applications may, however, be affected.
All users of glib2 should upgrade to these updated packages, which contain backported patches to 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 http://kbase.redhat.com/faq/docs/DOC-11259
5. Bugs fixed (http://bugzilla.redhat.com/):
474770 - CVE-2008-4316 glib2: integer overflows in the base64 handling functions (oCERT-2008-015)
