Alerta de Segurança Debian

DSA-273-1 krb4 -- fraqueza criptográfica

Data do Alerta:

28 Mar 2003

Pacotes Afetados:

Vulnerável:

Sim

Referência à base de dados de segurança:

No dicionário CVE do Mitre: CVE-2003-0138, CVE-2003-0139.
Alertas, notas de incidentes e vulnerabilidades do CERT: VU#623217, VU#442569.

Informações adicionais:

Uma fraqueza criptográfica na versão 4 do protocolo Kerberos permite que um atacante use um ataque "chosen-plaintext" para personificar qualquer principal em um domínio. Adicionalmente, a fraqueza criptográfica na implementação do krb4 permite o uso do ataque copiar-e-colar para fabricar tickets krb4 para clientes principais não autorizados se as chaves triple-DES forem usadas nos serviços krb4. Estes ataques podem ubverter toda a estrutura de autenticação de um domínio que use o Kerberos inteiramente.

Na distribuição estável (woody), este problema foi corrigido na versão 1.1-8-2.3.

Na antiga distribuição estável (potato), este problema foi corrigido na versão 1.0-2.3.

Na distribuição instável (sid), este problema foi corrigido na versão 1.2.2-1.

Nós recomendamos que você atualize seus pacotes krb4 imediatamente.

Corrigido em:

Debian GNU/Linux 2.2 (potato)
