CVE-2018-19857 (opens in a new tab)How to fix?
Upgrade Debian:9 vlc to version 3.0.6-0+deb9u1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream vlc package and not the vlc package as distributed by Debian.
See How to fix? for Debian:9 relevant fixed versions and status.
The CAF demuxer in modules/demux/caf.c in VideoLAN VLC media player 3.0.4 may read memory from an uninitialized pointer when processing magic cookies in CAF files, because a ReadKukiChunk() cast converts a return value to an unsigned int even if that value is negative. This could result in a denial of service and/or a potential infoleak.
