Informações adicionais:

Este alerta de segurança corrige o DSA 458-2 que causou um problema na rotina gethostbyaddr.

O alerta original dizia:

Sebastian Schmidt descobriu um buffer overflow na função getaddrinfo do Python, que pode permitir que um endereço IPV6, fornecido por um atacante remoto via DNS, sobrescreva a memória na pilha.

Esta falha existe somente no python 2.2 e 2.2.1, e apenas quando o suporte a IPv6 está desabilitado. O pacote python2.2 no Debian woody apresenta estas condições (o pacote 'python' não).

Na atual distribuição estável (woody) este problema foi corrigido na versão 2.2.1-4.6.

As distribuições testing e instável (sarge e sid) não foram afetadas por este problema.

Nós recomendamos que você atualize seus pacotes python2.2.

Corrigido em:

Debian GNU/Linux 3.0 (woody)
