xine is a GPL high-performance, portable and reusable multimedia
|
|
playback engine. xine-lib is xine's core engine. FFmpeg is a very fast

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 type="normal">
|
|
<p>
|
|
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.

There is no known workaround at this time.
