Vulnerabilidade  : estouros de pilha
CVE ID           : [3]CVE-2005-4048, 

Informações adicionais:
	
Simon Kilvington descobriu que imagens PNG especialmente preparadas podem
disparar um estouro de "heap" no libavcodec, a biblioteca multimídia do ffmpeg,
que pode levar à execução de código arbitrário.

A antiga distribuição estável ("woody") não contém o pacote ffmpeg.

Para a distribuição estável ("sarge") este problema foi corrigido na
versão 0.cvs20050313-2sarge1.

Para a distribuição instável ("sid") este problema foi corrigido na
versão 0.cvs20050918-5.1.

Recomendamos que você atualize seu pacote ffmpeg.

Corrigido em:
	
Debian GNU/Linux 3.1 (sarge)
