CVE-2013-4231: Libtiff

Medium severity, CVSS 4.3. EPSS: 7.4% chance of exploitation in the next 30 days.

Multiple buffer overflows in libtiff before 4.0.3 allow remote attackers to cause a denial of service (out-of-bounds write) via a crafted (1) extension block in a GIF image or (2) GIF raster image to tools/gif2tiff.c or (3) a long filename for a TIFF image to tools/rgb2ycbcr.c. NOTE: vectors 1 and 3 are disputed by Red Hat, which states that the input cannot exceed the allocated buffer size.

Affected products

• Libtiff Libtiff: up to and including 4.0.2; version 4.0 only; version 4.0.1 only
