Referência à base de dados de segurança:

No dicionário CVE do Mitre: CVE-2005-3191, CVE-2005-3192, CVE-2005-3193, CVE-2005-2097, CVE-2005-3624, CVE-2005-3625, CVE-2005-3626, CVE-2005-3627, CVE-2005-3628.

Informações adicionais:

"infamous41md" e Chris Evans descobriram vários estouros de pilha baseados em "heap" no xpdf, a suíte para Formato de Documentos Portáveis ("PDF"), que também está presente na libextractor, uma biblioteca para extrair meta dados arbitrários de arquivos, e que poderá levar a uma negação de serviço pela quebra da aplicação ou, possivelmente, a uma execução de código arbitrário.

A antiga distribuição estável ("woody") não contém pacotes libextractor.

Para a distribuição estável ("sarge") estes problemas foram corrigidos na versão 0.4.2-2sarge2.

Para a distribuição instável ("sid") estes problemas serão corrigidos logo.

Recomendamos que você atualize seus pacotes libextractor.

Corrigido em:

Debian GNU/Linux 3.1 (sarge)
