CVE-2012-3401

Impact: Moderate
Public: 2012-07-18
Bugzilla: 837577: CVE-2012-3401 libtiff (tiff2pdf): Heap-based buffer overflow due to improper initialization of T2P context struct pointer

Details

The MITRE CVE dictionary describes this issue as:

The t2p_read_tiff_init function in tiff2pdf (tools/tiff2pdf.c) in LibTIFF 4.0.2 and earlier does not properly initialize the T2P context struct pointer in certain error conditions, which allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted TIFF image that triggers a heap-based buffer overflow.
