CVE-2011-2484

Priority
Description
The add_del_listener function in kernel/taskstats.c in the Linux kernel
2.6.39.1 and earlier does not prevent multiple registrations of exit
handlers, which allows local users to cause a denial of service (memory and
CPU consumption), and bypass the OOM Killer, via a crafted application.
Ubuntu-Description
Vasiliy Kulikov discovered that taskstats listeners were not correctly
handled. A local attacker could expoit this to exhaust memory and CPU
resources, leading to a denial of service.
