Ubuntu 15.10 : linux vulnerabilities (USN-2930-1)

High Nessus Plugin ID 89934

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

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)

Ben Hawkes discovered an integer overflow in the Linux netfilter implementation. On systems running 32 bit kernels, a local unprivileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges. (CVE-2016-3135)

Ralf Spenneberg discovered that the USB driver for Clie devices in the Linux kernel did not properly sanity check the endpoints reported by the device. An attacker with physical access could cause a denial of service (system crash). (CVE-2015-7566)

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)

It was discovered that a race condition existed in the ioctl handler for the TTY driver in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or expose sensitive information. (CVE-2016-0723)

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)

Ralf Spenneberg discovered that the USB driver for Treo devices in the Linux kernel did not properly sanity check the endpoints reported by the device. An attacker with physical access could cause a denial of service (system crash). (CVE-2016-2782).

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.

Solution

Update the affected linux-image-4.2-generic, linux-image-4.2-generic-lpae and / or linux-image-4.2-lowlatency packages.
