USN-3021-2: Linux kernel (OMAP4) vulnerabilities

Ubuntu Security Notice USN-3021-2

27th June, 2016

linux-ti-omap4 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-ti-omap4
    – Linux kernel for OMAP4

Details

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)

Update instructions

The problem can be corrected by updating your system to the following
package version:

Ubuntu 12.04 LTS:
linux-image-3.2.0-1483-omap4

3.2.0-1483.110

To update your system, please follow these instructions:
https://wiki.ubuntu.com/Security/Upgrades.

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.

Security

Ubuntu Security Notice USN-3017-3

Ubuntu Security Notice 3017-3 – USN-3017-1 fixed vulnerabilities in the Linux kernel for Ubuntu 15.10. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 15.10 for Ubuntu 14.04 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. Various other issues were also addressed.

Ubuntu Security Notice USN-3016-4

Ubuntu Security Notice 3016-4 – USN-3016-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS.

Red Hat Security Advisory 2016-1345-01

Red Hat Security Advisory 2016-1345-01 – Red Hat JBoss BRMS is a business rules management system for the management, storage, creation, modification, and deployment of JBoss Rules. Security Fix: It was found that JGroups did not require necessary headers for encrypt and auth protocols from new nodes joining the cluster. An attacker could use this flaw to bypass security restrictions, and use this vulnerability to send and receive messages within the cluster, leading to information disclosure, message spoofing, or further possible attacks.
