Reporter Ubuntu Security Notice (C) 2009-2019 Canonical, Inc. / NASL script (C) 2009-2019 and is owned by Tenable, Inc. or an Affiliate thereof.

Description

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
