Informações adicionais:

Vários dissectores de pacotes no ethereal contem erros no manuseio de strings que podem ser explorados usando pacotes trabalhados maliciosamente para levar o ethereal a consumir quantidades excessivas de memória, cair, ou executar código arbitrariamente.

Essas vulnerabilidades foram anunciadas no seguinte alerta de segurança do Ethereal:

http://www.ethereal.com/appnotes/enpa-sa-00010.html

O Ethereal 0.9.4 no Debian 3.0 (woody) é afetado pela maioria dos problemas descrevidos no alerta, incluindo:

  • * O dissector DCERPC pode tentar alocar muita memória enquanto tenta decifrar uma string NDR.
  • * Tamanhos errados de prefixo IPv4 ou IPv6 podem causar um estouro no dissector OSI.
  • * A rotina tvb_get_nstringz0() manuseia incorretamente um um tamanho de buffer zerado.
  • * Os dissectores BGP, WTP, DNS, 802.11, ISAKMP, WSP, CLNP, e ISIS manuseiam strings de forma inapropriada.

Os seguintes problemas NÃO afetam essa versão:

  • * O dissector SPNEGO pode dar uma falha de segmentação enquanto tenta analisar um valor ASN.1 inválido.
  • * O dissector RMI manuseia strings de forma inapropriada.

Para a distribuição estável (woody) esses problemas foram corrigidos na versão 0.9.4-1woody5.

Para a antiga distribuição estável (potato) esses problemas serão corrigidos num alerta futuro.

Para a distribuição instável (sid) esses problemas foram corrigidos na versão 0.9.13-1.

Nós recomendamos que atualize seu pacote ethereal.

Corrigido em:

Debian GNU/Linux 3.0 (woody)
