========================================================================== Ubuntu Security Notice USN-2930-1 March 14, 2016
linux vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 15.10
Summary:
Several security issues were fixed in the kernel.
Software Description: - linux: Linux kernel
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)
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)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 15.10: linux-image-4.2.0-34-generic 4.2.0-34.39 linux-image-4.2.0-34-generic-lpae 4.2.0-34.39 linux-image-4.2.0-34-lowlatency 4.2.0-34.39 linux-image-4.2.0-34-powerpc-e500mc 4.2.0-34.39 linux-image-4.2.0-34-powerpc-smp 4.2.0-34.39 linux-image-4.2.0-34-powerpc64-emb 4.2.0-34.39 linux-image-4.2.0-34-powerpc64-smp 4.2.0-34.39
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
