Vulnerability Assessment Details

[GLSA-200601-06] xine-lib, FFmpeg: Heap-based buffer overflow

Vulnerability Assessment Summary
xine-lib, FFmpeg: Heap-based buffer overflow

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200601-06
(xine-lib, FFmpeg: Heap-based buffer overflow)


Simon Kilvington has reported a vulnerability in FFmpeg
libavcodec. The flaw is due to a buffer overflow error in the
"avcodec_default_get_buffer()" function. This function doesn't properly
handle specially crafted PNG files as a result of a heap overflow.

Impact

A remote attacker could entice a user to run an FFmpeg based
application on a maliciously crafted PNG file, resulting in the
execution of arbitrary code with the permissions of the user running
the application.

Workaround

There is no known workaround at this time.
