========================================================================== Ubuntu Security Notice USN-2908-2 February 22, 2016
linux-lts-wily vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 LTS
Summary:
Several security issues were fixed in the kernel.
Software Description: - linux-lts-wily: Linux hardware enablement kernel from Wily
Details:
halfdog discovered that OverlayFS, when mounting on top of a FUSE mount, incorrectly propagated file attributes, including setuid. A local unprivileged attacker could use this to gain privileges. (CVE-2016-1576)
halfdog discovered that OverlayFS in the Linux kernel incorrectly propagated security sensitive extended attributes, such as POSIX ACLs. A local unprivileged attacker could use this to gain privileges. (CVE-2016-1575)
It was discovered that the Linux kernel did not properly enforce rlimits for file descriptors sent over UNIX domain sockets. A local attacker could use this to cause a denial of service. (CVE-2013-4312)
It was discovered that the Linux kernel's Filesystem in Userspace (FUSE) implementation did not handle initial zero length segments properly. A local attacker could use this to cause a denial of service (unkillable task). (CVE-2015-8785)
Andy Lutomirski discovered a race condition in the Linux kernel's translation lookaside buffer (TLB) handling of flush events. A local attacker could use this to cause a denial of service or possibly leak sensitive information. (CVE-2016-2069)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.04 LTS: linux-image-4.2.0-30-generic 4.2.0-30.35~14.04.1 linux-image-4.2.0-30-generic-lpae 4.2.0-30.35~14.04.1 linux-image-4.2.0-30-lowlatency 4.2.0-30.35~14.04.1 linux-image-4.2.0-30-powerpc-e500mc 4.2.0-30.35~14.04.1 linux-image-4.2.0-30-powerpc-smp 4.2.0-30.35~14.04.1 linux-image-4.2.0-30-powerpc64-emb 4.2.0-30.35~14.04.1 linux-image-4.2.0-30-powerpc64-smp 4.2.0-30.35~14.04.1
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.
