This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 14.04 LTS for Ubuntu 12.04 LTS. It was discovered that the compression handling code in the Advanced Linux Sound Architecture (ALSA) subsystem in the Linux kernel did not properly check for an integer overflow. A local attacker could use this to cause a denial of service (system crash). (CVE-2014-9904) Kirill A. Shutemov discovered that memory manager in the Linux kernel did not properly handle anonymous pages. A local attacker could use this to cause a denial of service or possibly gain administrative privileges. (CVE-2015-3288) Vitaly Kuznetsov discovered that the Linux kernel did not properly suppress hugetlbfs support in X86 paravirtualized guests. An attacker in the guest OS could cause a denial of service (guest system crash). (CVE-2016-3961) 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)
