Description Laura Pardo 2018-05-02 19:15:53 UTC

A flaw was found in libvorbis 1.3.6. The mapping0_forward function in mapping0.c file in Xiph.Org does not validate the number of channels, which allows remote attackers to cause a denial of service (heap-based buffer overflow or over-read) via a crafted file.
