xine-lib is vulnerable to multiple buffer overflows when processing FLAC and ASF streams.
|Package||media-libs/xine-lib on all architectures|
|Affected versions||< 220.127.116.11|
|Unaffected versions||>= 18.104.22.168|
xine-lib is the core library package for the xine media player.
Damian Frizza and Alfredo Ortega (Core Security Technologies) discovered a stack-based buffer overflow within the open_flac_file() function in the file demux_flac.c when parsing tags within a FLAC file (CVE-2008-0486). A buffer overflow when parsing ASF headers, which is similar to CVE-2006-1664, has also been discovered (CVE-2008-1110).
A remote attacker could entice a user to play specially crafted FLAC or ASF video streams with a player using xine-lib, potentially resulting in the execution of arbitrary code with the privileges of the user running the player.
There is no known workaround at this time.
All xine-lib users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/xine-lib-22.214.171.124"
