CentOS Errata and Security Advisory CESA-2011:0318
The libtiff packages contain a library of functions for manipulating Tagged Image File Format (TIFF) files.
A heap-based buffer overflow flaw was found in the way libtiff processed certain TIFF Internet Fax image files, compressed with the CCITT Group 4 compression algorithm. 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-2011-0192)
Red Hat would like to thank Apple Product Security for reporting this issue.
All libtiff users should upgrade to these updated packages, which contain a backported patch to resolve this issue. All running applications linked against libtiff must be restarted for this update to take effect.
