Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200812-24 (VLC: Multiple vulnerabilities)

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 :

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 :

There is no known workaround at this time.

Solution

All VLC users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose '>=media-video/vlc-0.9.8a'
