This update fixes the CVEs described below.

  • CVE-2015-7550
    Dmitry Vyukov discovered a race condition in the keyring subsystem
    that allows a local user to cause a denial of service (crash).
  • CVE-2015-8543
    It was discovered that a local user permitted to create raw sockets
    could cause a denial-of-service by specifying an invalid protocol
    number for the socket. The attacker must have the CAP_NET_RAW
    capability.
  • CVE-2015-8575
    David Miller discovered a flaw in the Bluetooth SCO sockets
    implementation that leads to an information leak to local users.

In addition, this update fixes a regression in the previous update:

  • #808293

A regression in the UDP implementation prevented freeradius and
some other applications from receiving data.

For the oldoldstable distribution (squeeze), these problems have been
fixed in version 2.6.32-48squeeze18.

For the oldstable distribution (wheezy), these problems have been
fixed in version 3.2.73-2+deb7u2.

For the stable distribution (jessie), these problems have been fixed
in version 3.16.7-ckt20-1+deb8u2 or earlier.
