Summary
linux-lts-utopic vulnerabilities
Details

Ben Hawkes discovered that the Linux netfilter implementation did not correctly perform validation when handling IPT_SO_SET_REPLACE events. A local unprivileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges. (CVE-2016-3134)

It was discovered that the Linux kernel did not properly enforce rlimits for file descriptors sent over UNIX domain sockets. A local attacker could use this to cause a denial of service. (CVE-2013-4312)

It was discovered that a race condition existed when handling heartbeat- timeout events in the SCTP implementation of the Linux kernel. A remote attacker could use this to cause a denial of service. (CVE-2015-8767)

Andy Lutomirski discovered a race condition in the Linux kernel's translation lookaside buffer (TLB) handling of flush events. A local attacker could use this to cause a denial of service or possibly leak sensitive information. (CVE-2016-2069)

Andrey Konovalov discovered that the ALSA USB MIDI driver incorrectly performed a double-free. A local attacker with physical access could use this to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges. (CVE-2016-2384)

Dmitry Vyukov discovered that the Advanced Linux Sound Architecture (ALSA) framework did not verify that a FIFO was attached to a client before attempting to clear it. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-2543)

Dmitry Vyukov discovered that a race condition existed in the Advanced Linux Sound Architecture (ALSA) framework between timer setup and closing of the client, resulting in a use-after-free. A local attacker could use this to cause a denial of service. (CVE-2016-2544)

Dmitry Vyukov discovered a race condition in the timer handling implementation of the Advanced Linux Sound Architecture (ALSA) framework, resulting in a use-after-free. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-2545)

Dmitry Vyukov discovered race conditions in the Advanced Linux Sound Architecture (ALSA) framework's timer ioctls leading to a use-after-free. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-2546)

Dmitry Vyukov discovered that the Advanced Linux Sound Architecture (ALSA) framework's handling of high resolution timers did not properly manage its data structures. A local attacker could use this to cause a denial of service (system hang or crash) or possibly execute arbitrary code. (CVE-2016-2547, CVE-2016-2548)

Dmitry Vyukov discovered that the Advanced Linux Sound Architecture (ALSA) framework's handling of high resolution timers could lead to a deadlock condition. A local attacker could use this to cause a denial of service (system hang). (CVE-2016-2549)
