Ubuntu 12.04 LTS : linux vulnerabilities (USN-3021-1)

Ubuntu Security Notice (C) 2016 Canonical, Inc. / NASL script (C) 2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

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)

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)

Baozeng Ding discovered a use-after-free issue in the generic PPP
layer in the Linux kernel. A local attacker could use this to cause a
denial of service (system crash). (CVE-2016-4805)

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).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected packages.
