Background
VLC is a cross-platform media player and streaming server.
Description
VLC was found to have a buffer overflow when handling crafted MKV files.
Impact
A remote attacker could entice a user to open a specially crafted MKV file using VLC possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.
Workaround
There is no known workaround at this time.
Resolution
All VLC users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/vlc-3.0.12.1"
