CVE-2012-4564  (opens in a new tab)
CWE-122  (opens in a new tab)

How to fix?

Upgrade Centos:6 libtiff to version 0:3.9.4-9.el6_3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libtiff package and not the libtiff package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

ppm2tiff does not check the return value of the TIFFScanlineSize function, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted PPM image that triggers an integer overflow, a zero-memory allocation, and a heap-based buffer overflow.
