Descriptions

The Perl_reg_numbered_buff_fetch function in Perl 5.10.0, 5.12.0, 5.14.0, and other versions, when running with debugging enabled, allows context-dependent attackers to cause a denial of service (assertion failure and application exit) via crafted input that is not properly handled when using certain regular expressions, as demonstrated by causing SpamAssassin and OCSInventory to crash.

La función Perl_reg_numbered_buff_fetch en Perl 5.10.0, 5.12.0, 5.14.0 y otras versiones, cuando funciona con debugging activado, permite a atacantes dependientes de contexto causar una denegación de servicio (fallo de aserción y cierre de la aplicación) a través de una entrada manipulada que no es manejada adecuadamente cuando hace uso de ciertas expresiones regulares, como se ha demostrado causando la caída de SpamAssassin y OCSInventory.
