Vigil@nce - FFmpeg: buffer overflow of proresenc_kostya.c
September 2014 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
An attacker can generate a buffer overflow in proresenc_kostya.c
of Ffmpeg, in order to trigger a denial of service, and possibly
to execute code.
– Impacted products: Windows (platform), Unix (platform)
– Severity: 2/4
– Creation date: 18/08/2014
DESCRIPTION OF THE VULNERABILITY
The FFmpeg product is used to convert videos from one format to
another.
However, the routines encode_frame and encode_slice do not rightly
compare the actually needed size for the data to be processed and
the actually available size.
An attacker can therefore generate a buffer overflow in
proresenc_kostya.c of Ffmpeg, in order to trigger a denial of
service, and possibly to execute code.
