libtiff: Security Advisory - CVE-2012-4564
v2 changes:
* update format for commit log
* add Upstream-Status for patch
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.
