Descriptions

Perl 5.10.x allows context-dependent attackers to cause a denial of service (NULL pointer dereference and application crash) by leveraging an ability to inject arguments into a (1) getpeername, (2) readdir, (3) closedir, (4) getsockname, (5) rewinddir, (6) tell, or (7) telldir function call.

Perl v5.10.x permite a atacantes dependientes de contexto provocar una denegación del servicio (desreferencia a un puntero NULL y bloqueo de la aplicación) elevando una habilidad para inyectar argumentos en una llamada a la función (1) "getpeername", (2) "readdir", (3) "closedir", (4) "getsockname", (5) "rewinddir", (6) "tell", o (7) "telldir".
