Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation or denial-of-service.
Tetsuo Handa discovered that it is possible for a process to open far more files than the process' limit leading to denial-of-service conditions.
Ralf Spenneberg of OpenSource Security reported that the visor driver crashes when a specially crafted USB device without bulk-out endpoint is detected.
An SCTP denial-of-service was discovered which can be triggered by a local attacker during a heartbeat timeout event after the 4-way handshake.
A use-after-free vulnerability was discovered in the TIOCGETD ioctl. A local attacker could use this flaw for denial-of-service.
The Perception Point research team discovered a use-after-free vulnerability in the keyring facility, possibly leading to local privilege escalation.
For the stable distribution (jessie), these problems have been fixed in version 3.16.7-ckt20-1+deb8u3.
We recommend that you upgrade your linux packages.
