========================================================================== Ubuntu Security Notice USN-3169-1 January 11, 2017
linux vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.04 LTS
Summary:
Several security issues were fixed in the kernel.
Software Description: - linux: Linux kernel
Details:
Dmitry Vyukov discovered that the KVM implementation in the Linux kernel did not properly initialize the Code Segment (CS) in certain error cases. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2016-9756)
Andrey Konovalov discovered that signed integer overflows existed in the setsockopt() system call when handling the SO_SNDBUFFORCE and SO_RCVBUFFORCE options. A local attacker with the CAP_NET_ADMIN capability could use this to cause a denial of service (system crash or memory corruption). (CVE-2016-9793)
Baozeng Ding discovered a race condition that could lead to a use-after- free in the Advanced Linux Sound Architecture (ALSA) subsystem of the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-9794)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04 LTS: linux-image-4.4.0-59-generic 4.4.0-59.80 linux-image-4.4.0-59-generic-lpae 4.4.0-59.80 linux-image-4.4.0-59-lowlatency 4.4.0-59.80 linux-image-4.4.0-59-powerpc-e500mc 4.4.0-59.80 linux-image-4.4.0-59-powerpc-smp 4.4.0-59.80 linux-image-4.4.0-59-powerpc64-emb 4.4.0-59.80 linux-image-4.4.0-59-powerpc64-smp 4.4.0-59.80 linux-image-generic 4.4.0.59.62 linux-image-generic-lpae 4.4.0.59.62 linux-image-lowlatency 4.4.0.59.62 linux-image-powerpc-e500mc 4.4.0.59.62 linux-image-powerpc-smp 4.4.0.59.62 linux-image-powerpc64-emb 4.4.0.59.62 linux-image-powerpc64-smp 4.4.0.59.62
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.
