CVE-2018-19857
This could result in a denial of service and/or a potential infoleak.
CRITICAL 9.1EPSS 3.92%
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.92%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
