DSA-231-1 dhcp3 -- overflows de pilha

Data do Alerta:

17 Jan 2003

Pacotes Afetados:

Vulnerável:

Sim

Referência à base de dados de segurança:

No dicionário CVE do Mitre: CVE-2003-0026.
Alertas, notas de incidentes e vulnerabilidades do CERT: VU#284857, CA-2003-01.

Informações adicionais:

O Internet Software Consortium descobriu várias vulnerabilidades durante a autoria do daemon ISC DHCP. As vulnerabilidades existem em um erro da rotina de manipulação na biblioteca minires e talvez possam ser exploradas como um overflow de pilha. Isto pode permitir que um atacante remoto execute código arbitrário sob o id do usuário no qual o dhcp é executado, usualmente o root. Outros servidores parecem não ser afetados.

Na atual distribuição estável (woody) este problema foi corrigido na versão 3.0+3.0.1rc9-2.1.

A antiga distribuição estável (potato) não contém pacotes dhcp3.

Na distribuição instável (sid) este problema foi corrigido na versão 3.0+3.0.1rc11-1.

Nós recomendamos que você atualize seus pacotes dhcp3-server.

Corrigido em:

Debian GNU/Linux 3.0 (woody)
