USN-3021-1: Linux kernel vulnerabilities
27 June 2016
Several security issues were fixed in the kernel.
Releases
Packages
- linux - Linux kernel
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 versions:
Ubuntu 12.04
-
linux-image-3.2.0-105-powerpc64-smp
-
3.2.0-105.146
-
linux-image-3.2.0-105-generic-pae
-
3.2.0-105.146
-
linux-image-3.2.0-105-highbank
-
3.2.0-105.146
-
linux-image-3.2.0-105-generic
-
3.2.0-105.146
-
linux-image-3.2.0-105-virtual
-
3.2.0-105.146
-
linux-image-3.2.0-105-powerpc-smp
-
3.2.0-105.146
-
linux-image-3.2.0-105-omap
-
3.2.0-105.146
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.
