| Description: | Multiple vulnerabilities have been discovered in xine-lib, a library which supplies most of the application functionality of the xine multimedia player. The Common Vulnerabilities and Exposures project identifies the following three problems: Integer overflow vulnerabilities exist in xine's FLV, QuickTime, RealMedia, MVE and CAK demuxers, as well as the EBML parser used by the Matroska demuxer. These weaknesses allow an attacker to overflow heap buffers and potentially execute arbitrary code by supplying a maliciously crafted file of those types. Insufficient input validation in the Speex implementation used by this version of xine enables an invalid array access and the execution of arbitrary code by supplying a maliciously crafted Speex file. Inadequate bounds checking in the NES Sound Format (NSF) demuxer enables a stack buffer overflow and the execution of arbitrary code through a maliciously crafted NSF file. |
