Ubuntu 12.04 LTS : linux vulnerabilities (USN-3126-1)

Description

Ondrej Kozina discovered that the keyring interface in the Linux kernel contained a buffer overflow when displaying timeout events via the /proc/keys interface. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-7042) Dmitry Vyukov discovered a use-after-free vulnerability during error processing in the recvmmsg(2) implementation in the Linux kernel. A remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-7117). 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.
