========================================================================== Ubuntu Security Notice USN-2886-1 February 01, 2016
linux vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
Summary:
Several security issues were fixed in the kernel.
Software Description: - linux: Linux kernel
Details:
It was discovered that a use-after-free vulnerability existed in the AF_UNIX implementation in the Linux kernel. A local attacker could use crafted epoll_ctl calls to cause a denial of service (system crash) or expose sensitive information. (CVE-2013-7446)
It was discovered that the KVM implementation in the Linux kernel did not properly restore the values of the Programmable Interrupt Timer (PIT). A user-assisted attacker in a KVM guest could cause a denial of service in the host (system crash). (CVE-2015-7513)
éæ°žå discovered that the ppp implementation in the Linux kernel did not ensure that certain slot numbers are valid. A local attacker with the privilege to call ioctl() on /dev/ppp could cause a denial of service (system crash). (CVE-2015-7799)
Sasha Levin discovered that the Reliable Datagram Sockets (RDS) implementation in the Linux kernel had a race condition when checking whether a socket was bound or not. A local attacker could use this to cause a denial of service (system crash). (CVE-2015-7990)
It was discovered that the Btrfs implementation in the Linux kernel incorrectly handled compressed inline extants on truncation. A local attacker could use this to expose sensitive information. (CVE-2015-8374)
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 12.04 LTS: linux-image-3.2.0-98-generic 3.2.0-98.138 linux-image-3.2.0-98-generic-pae 3.2.0-98.138 linux-image-3.2.0-98-highbank 3.2.0-98.138 linux-image-3.2.0-98-omap 3.2.0-98.138 linux-image-3.2.0-98-powerpc-smp 3.2.0-98.138 linux-image-3.2.0-98-powerpc64-smp 3.2.0-98.138 linux-image-3.2.0-98-virtual 3.2.0-98.138
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.
