Alerta de Segurança Debian

DSA-207-1 tetex-bin -- execução de comando arbitrário

Data do Alerta:

11 Dez 2002

Pacotes Afetados:

tetex-bin

Vulnerável:

Sim

Referência à base de dados de segurança:

No dicionário CVE do Mitre: CVE-2002-0836.

Informações adicionais:

O time de segurança da SuSE descobriu uma vulnerabilidade na biblioteca kpathsea (libkpathsea) que é usada pelo xdvi e dvips. Ambos programas chamam a função system() inseguramente, o que permite que um atacante remoto execute comandos arbitrários através de arquivos DVI habilmente modificados.

Se o dvips é usado como um filtro de impressão, isto permite que um atacante local ou remoto com permissões de impressão execute código arbitrário como o usuário da impressora (geralmente lp).

Este problema foi corrigido na versão 1.0.7+20011202-7.1 para a atual distribuição estável (woody), na versão 1.0.6-7.3 para a antiga distribuição estável (potato) e na versão 1.0.7+20021025-4 para a distribuição instável (sid). Os pacotes xdvik-ja e dvipsk-ja também estão vulneráveis, mas chamam a biblioteca kpathsea dinamicamente e será corrigido automaticamente depois que uma nova ibkpathsea for instalada.

Nós recomendamos que você atualize seu pacote tetex-lib imediatamente.

Corrigido em:

Debian GNU/Linux 2.2 (potato)
