CVE-2018-19857 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:19.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream vlc package and not the vlc package as distributed by Ubuntu.
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.
