Description


Multiple vulnerabilities have been reported in FFmpeg, which can be exploited by malicious people to compromise an application using the library.

1) Array-indexing errors exist in the FLIC Video Decoder (libavcodec/flicvideo.c) component within the "flic_decode_frame_8BPP()" and "flic_decode_frame_15_16BPP()" functions. This can be exploited to corrupt heap-based memory e.g. via a specially crafted FLI or FLC file.

Successful exploitation may allow execution of arbitrary code.

2) An error exists within the handling of certain malformed RealMedia (*.rm) files, which can be exploited to corrupt heap-based memory via specially crafted RealMedia files.

3) An error exists within the handling of certain malformed Windows Media (*.wmv) files, which can be exploited to cause a memory corruption via specially crafted Windows Media files.
