## Description

libvorbis 1.1.2, and possibly other versions before 1.2.0, allows
context-dependent attackers to cause a denial of service via (1) an invalid
mapping type, which triggers an out-of-bounds read in the vorbis\_info\_clear
function in info.c, and (2) invalid blocksize values that trigger a
segmentation fault in the read function in block.c.
