Informações adicionais:

Vários problemas foram descobertos em clientes telnet, que poderiam ser explorados por daemons maliciosos aos quais os clientes se conectassem. O Common Vulnerabilities and Exposures project identificou os seguintes problemas:

  • CAN-2005-0468

    Gaël Delalleau descobriu um estouro de buffer na função env_opt_add() que permite a um atacante remoto executar código arbitrário.

  • CAN-2005-0469

    Gaël Delalleau descobriu um estouro de buffer ao lidar com as subopções LINEMODE em clientes telnet. Isto pode levar a execução de código arbitrário quando conectado a um servidor malicioso.

Na distribuição estável (woody), estes problemas foram corrigidos na versão 1.2.4-5woody8.

Na distribuição instável (sid), estes problemas foram corrigidos na versão 1.3.6-1.

Nós recomendamos que você atualize seu pacote krb5.

Corrigido em:

Debian GNU/Linux 3.0 (woody)
