CVE-2011-3619

Published: 17 October 2011

The apparmor_setprocattr function in security/apparmor/lsm.c in the Linux kernel before 3.0 does not properly handle invalid parameters, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact by writing to a /proc/#####/attr/current file.

From the Ubuntu Security Team

A flaw was discovered in the Linux kernel's AppArmor security interface when invalid information was written to it. An unprivileged local user could use this to cause a denial of service on the system.

Notes

Author	Note
apw	this was introduced in the version of apparmour in maverick and has already been fixed after that
