Pinkie Pie discovered a flaw in the Linux kernel’s futex subsystem. An unprivileged local user could exploit this flaw to cause a denial of service (system crash) or gain administrative privileges.
(CVE-2014-3153)
A flaw was discovered in the Linux kernel’s IPC reference counting. An unprivileged local user could exploit this flaw to cause a denial of service (OOM system crash). (CVE-2013-4483).
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.
