| Description: | Summary:
The remote host is missing an update for the 'linux-lts-trusty' package(s) announced via the USN-3018-2 advisory.
Vulnerability Insight:
USN-3018-1 fixed vulnerabilities in the Linux kernel for Ubuntu
14.04 LTS. This update provides the corresponding updates for the
Linux Hardware Enablement (HWE) kernel from Ubuntu 14.04 LTS for
Ubuntu 12.04 LTS.
Jesse Hertz and Tim Newsham discovered that the Linux netfilter
implementation did not correctly perform validation when handling 32 bit
compatibility IPT_SO_SET_REPLACE events on 64 bit platforms. A local
unprivileged attacker could use this to cause a denial of service (system
crash) or execute arbitrary code with administrative privileges.
(CVE-2016-4997)
Kangjie Lu discovered an information leak in the core USB implementation in
the Linux kernel. A local attacker could use this to obtain potentially
sensitive information from kernel memory. (CVE-2016-4482)
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)
Kangjie Lu discovered an information leak in the timer handling
implementation in the Advanced Linux Sound Architecture (ALSA) subsystem of
the Linux kernel. A local attacker could use this to obtain potentially
sensitive information from kernel memory. (CVE-2016-4569, CVE-2016-4578)
Kangjie Lu discovered an information leak in the X.25 Call Request handling
in the Linux kernel. A local attacker could use this to obtain potentially
sensitive information from kernel memory. (CVE-2016-4580)
It was discovered that an information leak exists in the Rock Ridge
implementation in the Linux kernel. A local attacker who is able to mount a
malicious iso9660 file system image could exploit this flaw to obtain
potentially sensitive information from kernel memory. (CVE-2016-4913)
Jesse Hertz and Tim Newsham discovered that the Linux netfilter
implementation did not correctly perform validation when handling
IPT_SO_SET_REPLACE events. A local unprivileged attacker could use this to
cause a denial of service (system crash) or obtain potentially sensitive
information from kernel memory. (CVE-2016-4998)
