Alerta de Segurança Debian

DSA-149-1 glibc -- overflow de inteiros

Data do Alerta:

13 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 com overflow de inteiros foi encontrada na biblioteca RPC usada pela GNU libc, que é derivada da biblioteca SunRPC. Essa falha pode ser explorada para obter acesso de root não autorizado a softwares que linkam esse código. Os pacotes a seguir também corrige overflows de inteiros no código malloc. Eles também contém uma correção do Andreas Schwab para reduzir o linebuflen juntamente com o crescimento do ponteiro para o buffer no código NSS DNS.

Esse problema foi corrigido na versão 2.1.3-23 para a antiga distribuição estável (potato), na versão 2.2.5-11.1 para a atual distribuição estável (woody) e na 2.2.5-13 para a distribuição (sid).

Nós recomendamos que você atualize seus pacotes libc6 imediatamente.

Corrigido em:

Debian GNU/Linux 2.2 (potato)
