oCERT-2008-004 multiple speex implementations insufficient boundary checks
Description:
The reference speex decoder from the Speex library performs insufficient boundary checks on a header structure read from user input, this has been reported in oCERT-2008-002 advisory.
Further investigation showed that several packages include similar code and are therefore vulnerable.
In order to prevent the usage of incorrect header processing reference code, the speex_packet_to_header() function has been modified to bound the returned mode values in Speex >= 1.2beta3.2. This change automatically fixes applications that use the Speex library dynamically.
Affected version:
gstreamer-plugins-good <= 0.10.7
SDL_sound <= 1.0.1
Speex <= 1.1.12 (speexdec)
Sweep <= 0.9.2
vorbis-tools <= 1.2.0
VLC Media Player <= 0.8.6f
xine-lib <= 1.11.1.1
XMMS speex plugin
Fixed version:
gstreamer-plugins-good >= 0.10.8 (patched in CVS)
SDL_sound >= 1.0.2
Speex >= 1.2beta3.2 (patched in CVS)
Sweep >= 0.9.3
vorbis-tools, patched in CVS
VLC Media Player, patched in GIT
xine-lib >= 1.1.12
XMMS speex plugin, N/A
