Informações adicionais:

Vários problemas foram descobertos na libtiff, a biblioteca Tag Image File Format para o processamento de arquivos gráficos no formato TIFF. Um atacante poderia preparar um gráfico TIFF especialmente construído que poderia fazer o cliente executar código arbitrário ou quebrar. O Projeto de Vulnerabilidades e Exposições Comuns identificou os seguintes problemas:

CAN-2004-0803
Chris Evans descobriu vários problemas nos decodificadores RLE (run lenght encoding) que podem levar à execução de código arbitrário.
CAN-2004-0804
Matthias Clasen descobriu uma divisão por zero através de um estouro de inteiro.
CAN-2004-0886
Dmitry V. Levin descobriu vários estouros de inteiro que causavam problemas de alocação de memória (malloc) que podem resultar em quebras ou corrupção de memória.

Para a distribuição estável (woody), estes problemas foram corrigidos na versão 3.5.5-6woody1.

Para a distribuição instável (sid), estes problemas foram corrigidos na versão 3.6.1-2.

Nós recomendamos que você atualize seu pacote libtiff.

Corrigido em:

Debian GNU/Linux 3.0 (woody)
