## Description

The msrle\_decode\_8\_16\_24\_32 function in msrledec.c in libavcodec in FFmpeg
through 1.1.3 does not properly determine certain end pointers, which
allows remote attackers to cause a denial of service (out-of-bounds array
access and application crash) or possibly have unspecified other impact via
crafted Microsoft RLE data.
