-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: libpng security update Advisory ID: RHSA-2011:1103-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-1103.html Issue date: 2011-07-28 CVE Names: CVE-2011-2692 ===================================================================== 1. Summary: Updated libpng and libpng10 packages that fix one security issue are now available for Red Hat Enterprise Linux 4. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 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: The libpng packages contain a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files. An uninitialized memory read issue was found in the way libpng processed certain PNG images that use the Physical Scale (sCAL) extension. An attacker could create a specially-crafted PNG image that, when opened, could cause an application using libpng to crash. (CVE-2011-2692) Users of libpng and libpng10 should upgrade to these updated packages, which contain a backported patch to correct this issue. All running applications using libpng or libpng10 must be restarted for the update to take effect. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259 5. Bugs fixed (http://bugzilla.redhat.com/): 720612 - CVE-2011-2692 libpng: Invalid read when handling empty sCAL chunks 6.
