DescriptionSecunia reports :
Simon Kilvington has reported a vulnerability in FFmpeg libavcodec, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially to compromise a user's system.
The vulnerability is caused due to a boundary error in the 'avcodec_default_get_buffer()' function of 'utils.c' in libavcodec.
This can be exploited to cause a heap-based buffer overflow when a specially crafted 1x1 '.png' file containing a palette is read.
SolutionUpdate the affected packages.
