Vulnerability from fkie_nvd - Published: 2018-12-05 11:29 - Updated: 2026-06-17 01:50
Severity
Summary
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.
