========================================================================== Ubuntu Security Notice USN-3099-1 October 11, 2016
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:
VladimÃr BeneÅ¡ discovered an unbounded recursion in the VLAN and TEB Generic Receive Offload (GRO) processing implementations in the Linux kernel, A remote attacker could use this to cause a stack corruption, leading to a denial of service (system crash). (CVE-2016-7039)
Marco Grassi discovered a use-after-free condition could occur in the TCP retransmit queue handling code in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-6828)
Pengfei Wang discovered a race condition in the s390 SCLP console driver for the Linux kernel when handling ioctl()s. A local attacker could use this to obtain sensitive information from kernel memory. (CVE-2016-6130)
Pengfei Wang discovered a race condition in the Adaptec AAC RAID controller driver in the Linux kernel when handling ioctl()s. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-6480)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04 LTS: linux-image-4.4.0-42-generic 4.4.0-42.62 linux-image-4.4.0-42-generic-lpae 4.4.0-42.62 linux-image-4.4.0-42-lowlatency 4.4.0-42.62 linux-image-4.4.0-42-powerpc-e500mc 4.4.0-42.62 linux-image-4.4.0-42-powerpc-smp 4.4.0-42.62 linux-image-4.4.0-42-powerpc64-emb 4.4.0-42.62 linux-image-4.4.0-42-powerpc64-smp 4.4.0-42.62
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.
