Red Hat: RHSA-2012:1054-01 Critical: libtiff Buffer Overflow

red hat
Calendar Grey July 3, 2012
Dist Redhat Esm H88
Ubuntu releases important security updates for libpng in advisory USN-2012-1234-01, essential for all users.
Updated libtiff packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5 and 6

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/articles/11258

Summary

The libtiff packages contain a library of functions for manipulating Tagged Image File Format (TIFF) files.
libtiff did not properly convert between signed and unsigned integer values, leading to a buffer overflow. An attacker could use this flaw to create a specially-crafted TIFF file that, when opened, would cause an application linked against libtiff to crash or, possibly, execute arbitrary code. (CVE-2012-2088)
Multiple integer overflow flaws, leading to heap-based buffer overflows, were found in the tiff2pdf tool. An attacker could use these flaws to create a specially-crafted TIFF file that would cause tiff2pdf to crash or, possibly, execute arbitrary code. (CVE-2012-2113)
All libtiff users should upgrade to these updated packages, which contain backported patches to resolve these issues. All running applications linked against libtiff must be restarted for this update to take effect.
