Descriptions

The proc_open function in ext/standard/proc_open.c in PHP before 5.2.11 and 5.3.x before 5.3.1 does not enforce the (1) safe_mode_allowed_env_vars and (2) safe_mode_protected_env_vars directives, which allows context-dependent attackers to execute programs with an arbitrary environment via the env parameter, as demonstrated by a crafted value of the LD_LIBRARY_PATH environment variable.

La función proc_open en ext/standard/proc_open.c en PHP anterior a v5.2.11 y v5.3.x anterior a v5.3.1 no aplica adecuadamente las directivas (1) safe_mode_allowed_env_vars y (2) safe_mode_protected_env_vars, lo que permite dependientes del contexto a atacantes ejecutar programas con un entorno de su elección a través del parámetro env, como se ha demostrado por un valor manipulado de la variable del entorno LD_LIBRARY_PATH.
