Details

Tavis Ormandy and Julien Tinnes discovered that Linux did not correctly
initialize certain socket operation function pointers. A local attacker
could exploit this to gain root privileges. By default, Ubuntu 8.04
and later with a non-zero /proc/sys/vm/mmap_min_addr setting were not
vulnerable.
