Sasha Levin reported a flaw in the Linux kernel’s point-to-point protocol (PPP) when used with the Layer Two Tunneling Protocol (L2TP).
A local user could exploit this flaw to gain administrative privileges. (CVE-2014-4943)
An flaw was discovered in the Linux kernel’s audit subsystem when auditing certain syscalls. A local attacker could exploit this flaw to obtain potentially sensitive single-bit values from kernel memory or cause a denial of service (OOPS). (CVE-2014-3917)
Don Bailey discovered a flaw in the LZO decompress algorithm used by the Linux kernel. An attacker could exploit this flaw to cause a denial of service (memory corruption or OOPS). (CVE-2014-4608).
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.
