Descriptions

The pfs_getextattr function in FreeBSD 7.x before 7.3-RELEASE and 8.x before 8.0-RC1 unlocks a mutex that was not previously locked, which allows local users to cause a denial of service (kernel panic), overwrite arbitrary memory locations, and possibly execute arbitrary code via vectors related to opening a file on a file system that uses pseudofs.

La función pfs_getextattr en FreeBSD v7.x antes de v7.3-RELEASE y v8.x antes de v8.0 RC1 desbloquea un mutex que no ha sido cerrado anteriormente, lo que permite a usuarios locales causar una denegación de servicio (kernel panic), sobrescribir cualquier ubicación de memoria, y posiblemente ejecutar código de su elección a través de vectores relacionados con la apertura de un archivo en un sistema de archivos que utiliza pseudofs.
