Descriptions

The shell_quote function in python-gnupg 0.3.5 does not properly quote strings, which allows context-dependent attackers to execute arbitrary code via shell metacharacters in unspecified vectors, as demonstrated using "$(" command-substitution sequences, a different vulnerability than CVE-2014-1928. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-7323.

La función shell_quote en python-gnupg 0.3.5 no cita debidamente cadenas, lo que permite a atacantes dependientes de contexto ejecutar código arbitrario a través de metacaracteres de shell en vectores no especificados, tal y como fue demostrado mediante el uso de secuencias de sustitución de comandos '$(', una vulnerabilidad diferente a CVE-2014-1928. NOTA: esta vulnerabilidad existe debido a una solución incompleta para CVE-2013-7323.

Multiple vulnerabilities were discovered in the Python wrapper for the Gnu Privacy Guard (GPG). Insufficient sanitising could lead to the execution of arbitrary shell commands.
