========================================================================== Ubuntu Security Notice USN-3001-1 June 10, 2016
linux-lts-vivid 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-vivid: Linux hardware enablement kernel from Vivid for Trusty
Details:
Justin Yackoski discovered that the Atheros L2 Ethernet Driver in the Linux kernel incorrectly enables scatter/gather I/O. A remote attacker could use this to obtain potentially sensitive information from kernel memory. (CVE-2016-2117)
Jann Horn discovered that eCryptfs improperly attempted to use the mmap() handler of a lower filesystem that did not implement one, causing a recursive page fault to occur. A local unprivileged attacker could use to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges. (CVE-2016-1583)
Jason A. Donenfeld discovered multiple out-of-bounds reads in the OZMO USB over wifi device drivers in the Linux kernel. A remote attacker could use this to cause a denial of service (system crash) or obtain potentially sensitive information from kernel memory. (CVE-2015-4004)
Ralf Spenneberg discovered that the Linux kernel's GTCO digitizer USB device driver did not properly validate endpoint descriptors. An attacker with physical access could use this to cause a denial of service (system crash). (CVE-2016-2187)
Hector Marco and Ismael Ripoll discovered that the Linux kernel would improperly disable Address Space Layout Randomization (ASLR) for x86 processes running in 32 bit mode if stack-consumption resource limits were disabled. A local attacker could use this to make it easier to exploit an existing vulnerability in a setuid/setgid program. (CVE-2016-3672)
Andrey Konovalov discovered that the CDC Network Control Model USB driver in the Linux kernel did not cancel work events queued if a later error occurred, resulting in a use-after-free. An attacker with physical access could use this to cause a denial of service (system crash). (CVE-2016-3951)
It was discovered that an out-of-bounds write could occur when handling incoming packets in the USB/IP implementation in the Linux kernel. A remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-3955)
Vitaly Kuznetsov discovered that the Linux kernel did not properly suppress hugetlbfs support in X86 paravirtualized guests. An attacker in the guest OS could cause a denial of service (guest system crash). (CVE-2016-3961)
Kangjie Lu discovered an information leak in the ANSI/IEEE 802.2 LLC type 2 Support implementations in the Linux kernel. A local attacker could use this to obtain potentially sensitive information from kernel memory. (CVE-2016-4485)
Kangjie Lu discovered an information leak in the routing netlink socket interface (rtnetlink) implementation in the Linux kernel. A local attacker could use this to obtain potentially sensitive information from kernel memory. (CVE-2016-4486)
Jann Horn discovered that the InfiniBand interfaces within the Linux kernel could be coerced into overwriting kernel memory. A local unprivileged attacker could use this to possibly gain administrative privileges on systems where InifiniBand related kernel modules are loaded. (CVE-2016-4565)
It was discovered that in some situations the Linux kernel did not handle propagated mounts correctly. A local unprivileged attacker could use this to cause a denial of service (system crash). (CVE-2016-4581)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.04 LTS: linux-image-3.19.0-61-generic 3.19.0-61.69~14.04.1 linux-image-3.19.0-61-generic-lpae 3.19.0-61.69~14.04.1 linux-image-3.19.0-61-lowlatency 3.19.0-61.69~14.04.1 linux-image-3.19.0-61-powerpc-e500mc 3.19.0-61.69~14.04.1 linux-image-3.19.0-61-powerpc-smp 3.19.0-61.69~14.04.1 linux-image-3.19.0-61-powerpc64-emb 3.19.0-61.69~14.04.1 linux-image-3.19.0-61-powerpc64-smp 3.19.0-61.69~14.04.1
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.
