Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
Multiple vulnerabilities in VLC may lead to the remote execution of
arbitrary code.
Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
VLC is a cross-platform media player and streaming server.
Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-video/vlc < 0.9.8a >=3D 0.9.8a
Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Tobias Klein reported the following vulnerabilities:
* A stack-based buffer overflow when processing CUE image files in
modules/access/vcd/cdrom.c (CVE-2008-5032).
* A stack-based buffer overflow when processing RealText (.rt)
subtitle files in the ParseRealText() function in
modules/demux/subtitle.c (CVE-2008-5036).
* An integer overflow when processing RealMedia (.rm) files in the
ReadRealIndex() function in real.c in the Real demuxer plugin,
leading to a heap-based buffer overflow (CVE-2008-5276).
Impact
=3D=3D=3D=3D=3D=3D
A remote attacker could entice a user to open a specially crafted CUE
image file, RealMedia file or RealText subtitle file, possibly
resulting in the execution of arbitrary code with the privileges of the
user running the application.
Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
There is no known workaround at this time.
Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
All VLC users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=3Dmedia-video/vlc-0.9.8a"
