MGASA-2012-0332
Date: 	November 17th, 2012
Affected releases: 	1, 2


Description:
Updated libtiff packages fix security vulnerability:

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
(CVE-2012-4564).

lib(64)tiff3-3.9.5-1.7.mga1
