LibTIFF ppm2tiff buffer overflow
|libtiff-ppm2tiff-bo (79750)||High Risk|
LibTIFF is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the ppm2tiff utility when parsing images. By persuading a victim to open a specially-crafted PPM image file, a remote attacker could exploit this vulnerability to overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the affected application to crash.
Apply the appropriate update for your system. See References.

- CVE-2012-4564: 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.
