DSA-183-1 krb5 -- buffer overflow

Data do Alerta:

29 Out 2002

Pacotes Afetados:

Vulnerável:

Sim

Referência à base de dados de segurança:

No dicionário CVE do Mitre: CVE-2002-1235.
Alertas, notas de incidentes e vulnerabilidades do CERT: CA-2002-29, VU#875073.

Informações adicionais:

Tom Yu e Sam Hartman do MIT descobriram outro buffer overflow na pilha da função kadm_ser_wrap_in do servidor de administração Kerberos v4. Esta falha do kadmind tem um exploit em circulação e portanto, é considerada séria. A implementação do krb5 do MIT inclui suporte para a versão 4, incluindo uma biblioteca v4 completa, suporte no servidor para o krb4 e suporte limitado para o cliente v4.

Este problema foi corrigido na versão 1.2.4-5woody3 para a atual distribuição estável (woody) e na versão 1.2.6-2 para a distribuição instável (sid). A antiga distribuição estável (potato) não é afetada, uma vez que não há pacotes krb5 incluídos.

Nós recomendamos que você atualize seus pacotes krb5 imediatamente.

Corrigido em:

Debian GNU/Linux 3.0 (woody)
