## Description

The StripTags function in (1) the USF decoder
(modules/codec/subtitles/subsdec.c) and (2) the Text decoder
(modules/codec/subtitles/subsusf.c) in VideoLAN VLC Media Player 1.1 before
1.1.6-rc allows remote attackers to execute arbitrary code via a subtitle
with an opening "<" without a closing ">" in an MKV file, which triggers
heap memory corruption, as demonstrated using
