========================================================================== Ubuntu Security Notice USN-2910-2 February 27, 2016
linux-lts-vivid regression ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 LTS
Summary:
USN-2910-1 introduced a regression in the Ubuntu 15.04 Linux kernel backported to Ubuntu 14.04 LTS.
Software Description: - linux-lts-vivid: Linux hardware enablement kernel from Vivid for Trusty
Details:
USN-2910-1 fixed vulnerabilities in the Ubuntu 15.04 Linux kernel backported to Ubuntu 14.04 LTS. An incorrect locking fix caused a regression that broke graphics displays for Ubuntu 14.04 LTS guests running the Ubuntu 15.04 backport kernel within VMWare virtual machines. This update fixes the problem.
We apologize for the inconvenience.
Original advisory 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 keyring subsystem contained a race between read and revoke operations. A local attacker could use this to cause a denial of service (system crash). (CVE-2015-7550)
éæ°žå discovered that the Linux kernel networking implementation did not validate protocol identifiers for certain protocol families, A local attacker could use this to cause a denial of service (system crash) or possibly gain administrative privileges. (CVE-2015-8543)
Dmitry Vyukov discovered that the pptp implementation in the Linux kernel did not verify an address length when setting up a socket. A local attacker could use this to craft an application that exposed sensitive information from kernel memory. (CVE-2015-8569)
David Miller discovered that the Bluetooth implementation in the Linux kernel did not properly validate the socket address length for Synchronous Connection-Oriented (SCO) sockets. A local attacker could use this to expose sensitive information. (CVE-2015-8575)
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)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.04 LTS: linux-image-3.19.0-51-generic 3.19.0-51.58~14.04.1 linux-image-3.19.0-51-generic-lpae 3.19.0-51.58~14.04.1 linux-image-3.19.0-51-lowlatency 3.19.0-51.58~14.04.1 linux-image-3.19.0-51-powerpc-e500mc 3.19.0-51.58~14.04.1 linux-image-3.19.0-51-powerpc-smp 3.19.0-51.58~14.04.1 linux-image-3.19.0-51-powerpc64-emb 3.19.0-51.58~14.04.1 linux-image-3.19.0-51-powerpc64-smp 3.19.0-51.58~14.04.1
After a standard system update you need to reboot your computer to make all the necessary changes.
