Red Hat Enterprise Linux 5 and 6: Urgent Update for libtiff Buffer Overflow

red hat
Calendar Grey April 10, 2012
Scroller Redhat
An important security patch for libtiff has been released, resolving critical vulnerabilities found in Red Hat Enterprise Linux versions 5 and 6.
Updated libtiff packages that fix two 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.
Two integer overflow flaws, leading to heap-based buffer overflows, were found in the way libtiff attempted to allocate space for a tile in a TIFF image file. An attacker could use these flaws 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-2012-1173)
All libtiff users should upgrade to these updated packages, which contain a backported patch to resolve these issues. All running applications linked against libtiff must be restarted for this update to take effect.
