Data do Alerta:

06 Mar 2006

Pacotes Afetados:

gnutls11

Vulnerável:

Sim

Referência à base de dados de segurança:

Na base de dados do BugTraq (na SecurityFocus): ID BugTraq 16568.
No dicionário CVE do Mitre: CVE-2006-0645.

Informações adicionais:

Evgeny Legerov descobriu vários acessos de memória fora dos limites no componente decodificador DER da Biblioteca Tiny ASN.1, que também está presente e é utilizada no GnuTLS, a implementação GNU para os protocolos Camada de Transporte Segura ("Transport Layer Security - TLS") 1.0 e Camada de Soquete Segura ("Secure Sockets Layer - SSL") 3.0, que permitem que atacantes quebrem ("crash") o decodificador DER e possivelmente executem código arbitrário.

A antiga distribuição estável ("woody") não é afetada por estes problemas.

Para a distribuição estável ("sarge") estes problemas foram corrigidos na versão 1.0.16-13.2.

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

Recomendamos que você atualize seus pacotes gnutls.

Corrigido em:

Debian GNU/Linux 3.1 (sarge)
