|Title:||RedHat Update for libpng RHSA-2011:1105-01|
|Summary:||The remote host is missing an update for the 'libpng'; package(s) announced via the referenced advisory.|
The remote host is missing an update for the 'libpng'
package(s) announced via the referenced advisory.
The libpng packages contain a library of functions for creating and
manipulating PNG (Portable Network Graphics) image format files.
A buffer overflow flaw was found in the way libpng processed certain PNG
image files. An attacker could create a specially-crafted PNG image that,
when opened, could cause an application using libpng to crash or,
potentially, execute arbitrary code with the privileges of the user running
the application. (CVE-2011-2690)
Note: The application behavior required to exploit CVE-2011-2690 is rarely
used. No application shipped with Red Hat Enterprise Linux behaves this
way, for example.
An out-of-bounds memory read flaw was found in the way libpng processed
certain PNG image files. An attacker could create a specially-crafted PNG
image that, when opened, could cause an application using libpng to crash.
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 should upgrade to these updated packages, which upgrade
libpng to version 1.2.46 to correct these issues. All running applications
using libpng must be restarted for the update to take effect.
libpng on Red Hat Enterprise Linux Desktop (v. 6),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)
Please Install the Updated Packages.
