VLC is a cross-platform media player and streaming server.
A buffer overflow was discovered in the DecodeAdpcmImaQT function in modules/codec/adpcm.c in the VideoLAN VLC media player.
Remote attackers, by enticing a user to execute a specially crafted QuickTime IMA file, could cause a Denial of Service condition or possibly execute arbitrary code.
There is no known workaround at this time.
All VLC users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/vlc-2.2.4"
