Alerta de Segurança Debian

DSA-143-1 krb5 -- overflow de inteiros

Data do Alerta:

05 Ago 2002

Pacotes Afetados:

Vulnerável:

Sim

Referência à base de dados de segurança:

Na base de dados do BugTraq (na SecurityFocus): ID BugTraq 5356.
No dicionário CVE do Mitre: CVE-2002-0391.
Alertas, notas de incidentes e vulnerabilidades do CERT: VU#192995.

Informações adicionais:

Uma falha de overflow de inteiros foi encontrada na biblioteca RPC, usada na administração de sistemas Kerberos 5, que é derivada da biblioteca SunRPC. Essa falha pode ser explorada para obter acesso de root não autorizado em uma máquina KDC. Acredita-se que o atacante precise autenticar no daemon kadmin para que o ataque seja realizado com sucesso. Nenhum exploit é conhecido ainda.

Esse problema foi corrigido na versão 1.2.4-5woody1 para a atual distribuição estável (woody) e na versão 1.2.5-2 da distribuição instável (sid). O Debian 2.2 (potato) não foi afetado uma vez que não contém pacotes krb5.

Nós recomendamos que você atualize seus pacotes kerberos imediatamente.

Corrigido em:

Debian GNU/Linux 3.0 (woody)
