DSA-976-1 libast -- estouro de pilha

Data do Alerta:

15 Fev 2006

Pacotes Afetados:

libast, libast1

Vulnerável:

Sim

Referência à base de dados de segurança:

No dicionário CVE do Mitre: CVE-2006-0224.

Informações adicionais:

Johnny Mast descobriu um estouro de pilha na libast, a biblioteca de "assorted spiffy things" ("coisas sortidas da moda"), que pode levar à execução de código arbitrário. Esta biblioteca é utilizada pelo eterm quando instalado com "setgid uid" que leva à vulnerabilidade de alterar o arquivo utmp.

Para a antiga distribuição estável ("woody") este problema foi corrigido na versão 0.4-3woody2.

Para a distribuição estável ("sarge") este problema foi corrigido na versão 0.6-0pre2003010606sarge1.

Para a distribuição instável ("sid") este problema será corrigido em breve.

Recomendamos que você atualize seus pacotes libast.

Corrigido em:

Debian GNU/Linux 3.0 (woody)
