The SuSe Linux version of LibTIFF is vulnerable to a buffer overflow that may allow a remote attacker to execute arbitrary code.
SuSe LibTIFF is a library used to encode and decode images in Tag Image File Format (TIFF) format on SuSE systems. A lack of input validation in the OJPEG (old JPEG) handling routine, OJPEGVSetField (in libtiff/tif_ojpeg.c), may cause a heap-based buffer overflow. Consequently, a remote attacker may be able to exploit this vulnerability by supplying an application using LibTIFF with a specially crafted TIFF image.
Please note that OJPEG support is enabled by default in versions of the SuSE LibTIFF library without the latest security updates (announced at SUSE-SA:2004:038) installed.
If a remote attacker can persuade a user to access a specially crafted TIFF image, that attacker may be able to execute arbitrary code with the privileges of the application linked to LibTIFF.
Disable OJPEG support
