Alerta de Segurança Debian
DSA-262-1 samba -- exploração remota
- Data do Alerta:
- 15 Mar 2003
- Pacotes Afetados:
- samba
- Vulnerável:
- Sim
- Referência à base de dados de segurança:
- Na base de dados do BugTraq (na SecurityFocus): ID BugTraq 7107, ID BugTraq 7106.
No dicionário CVE do Mitre: CVE-2003-0085, CVE-2003-0086. - Informações adicionais:
-
Sebastian Krahmer da equipe de auditoria de segurança da SuSE encontrou dois problemas no samba, uma implementação popular do SMB/CIFS. Os problemas são:
- Um estouro de buffer no fragmento de pacote SMB/CIFS do código re-assembly usado pelo smbd. Como o smbd roda como root um atacante remoto pode utilizar isso para obter acesso de root à máquina rodando o smbd.
- O código para escrever arquivos reg está vulnerável ao comando chown e pode ser possível para um usuário local sobrescrever arquivos so sistema.
Ambos os problemas foram corrigidos na versão upstream(*) 2.2.8, e na versão 2.2.3a-12.1 para a distribuição Debian GNU/Linux 3.0/woody.
Nós recomendamos que atualize seu pacote samba imediatamente.
