Vigil@nce - Libav: integer overflow of av_lzo1x_decode
July 2014 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
An attacker can generate an integer overflow in the
av_lzo1x_decode() function of Libav, in order to trigger a denial
of service, and possibly to execute code.
Impacted products: Debian, MBS, Unix (platform)
Severity: 2/4
Creation date: 27/06/2014
DESCRIPTION OF THE VULNERABILITY
The Libav library implements the LZO compression algorithm.
However, if data contains a null byte, an integer can overflow in
the av_lzo1x_decode() function of the libavutil/lzo.c file.
An attacker can therefore generate an integer overflow in the
av_lzo1x_decode() function of Libav, in order to trigger a denial
of service, and possibly to execute code.
