escalate privileges. (CVE-2011-2182)
Vasiliy Kulikov discovered that taskstats listeners were not correctly
handled. A local attacker could exploit this to exhaust memory and CPU
resources, leading to a denial of service. (CVE-2011-2484)
Sami Liedes discovered that ext4 did not correctly handle missing root
inodes. A local attacker could trigger the mount of a specially crafted
filesystem to cause the system to crash, leading to a denial of service.
(CVE-2011-2493)
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. (CVE-2011-3619)
Scot Doyle discovered that the bridge networking interface incorrectly
handled certain network packets. A remote attacker could exploit this to
crash the system, leading to a denial of service. (CVE-2011-4087)
