Descriptions

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 refined-australia-blu720p-sample.mkv.

La función StripTags en (1) el decodificador USF (modules/codec/subtitles/subsdec.c) y (2) el decodificador de texto (modules/codec/subtitles/subsusf.c) en VideoLAN VLC Media Player 1.1 antes de v1.1.6- rc permite a atacantes remotos ejecutar código arbitrario a través de un subtítulo con una abertura "<" sin cierre ">" en un fichero MKV, que provoca daños en la memoria dinámica, como lo demuestra el uso refined-australia-blu720p-sample.mkv.

Multiple vulnerabilities have been found in VLC, the worst of which could lead to user-assisted execution of arbitrary code. Versions less than 2.1.2 are affected.
