Descriptions

The do_replace function in net/bridge/netfilter/ebtables.c in the Linux kernel before 2.6.39 does not ensure that a certain name field ends with a '\0' character, which allows local users to obtain potentially sensitive information from kernel stack memory by leveraging the CAP_NET_ADMIN capability to replace a table, and then reading a modprobe command line.

La función de do_replace en net/bridge/netfilter/ebtables.c en versiones del kernel de Linux anteriores a v2.6.39 no garantiza que un nombre de campo determinado termine con un '\0', lo que permite a usuarios locales obtener información sensible de la pila del kernel aprovechandose de la capacidad CAP_NET_ADMIN para reemplazar a una tabla y luego leer una línea de comandos modprobe.
