Description
This security bulletin contains information about 1 security vulnerability.
1) Input validation error (CVE-ID: CVE-2012-1173)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
Multiple integer overflows in tiff_getimage.c in LibTIFF 3.9.4 allow remote attackers to execute arbitrary code via a crafted tile size in a TIFF file, which is not properly handled by the (1) gtTileSeparate or (2) gtStripSeparate function, leading to a heap-based buffer overflow.
