USN-2927-1: graphite2 vulnerabilities
Ubuntu Security Notice USN-2927-1
14th March, 2016
graphite2 vulnerabilities
A security issue affects these releases of Ubuntu and its
derivatives:
- Ubuntu 15.10
- Ubuntu 14.04 LTS
Summary
graphite2 could be made to crash or run programs as your login if it opened
a specially crafted font.
Software description
- graphite2
– Font rendering engine for Complex Scripts
Details
It was discovered that graphite2 incorrectly handled certain malformed
fonts. If a user or automated system were tricked into opening a specially-
crafted font file, a remote attacker could use this issue to cause
graphite2 to crash, resulting in a denial of service, or possibly execute
arbitrary code.
Update instructions
The problem can be corrected by updating your system to the following
package version:
- Ubuntu 15.10:
-
libgraphite2-3
1.3.6-1ubuntu0.15.10.1
- Ubuntu 14.04 LTS:
-
libgraphite2-3
1.3.6-1ubuntu0.14.04.1
To update your system, please follow these instructions:
https://wiki.ubuntu.com/Security/Upgrades.
This update uses a new upstream release, which includes additional bug
fixes. After a standard system update you need to restart applications
using graphite2, such as LibreOffice, to make all the necessary changes.

linux vulnerability
A security issue affects these releases of Ubuntu and its
derivatives:
- Ubuntu 12.04 LTS
Summary
The system could be made to crash or run programs as an administrator by
someone with physical access.
Software description

Details
Andrey Konovalov discovered that the ALSA USB MIDI driver incorrectly
performed a double-free. A local attacker with physical access could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code with administrative privileges.
Update instructions
The problem can be corrected by updating your system to the following
package version:
- Ubuntu 12.04 LTS:

3.2.0-101.141
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.

Summary
Several security issues were fixed in the kernel.
Software description

– Linux kernel
Details
Ben Hawkes 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 possibly execute arbitrary code with administrative
privileges. (CVE-2016-3134)
Ben Hawkes discovered an integer overflow in the Linux netfilter
implementation. On systems running 32 bit kernels, a local unprivileged
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code with administrative privileges.
(CVE-2016-3135)
Ralf Spenneberg discovered that the USB driver for Clie devices in the
Linux kernel did not properly sanity check the endpoints reported by the
device. An attacker with physical access could cause a denial of service
(system crash). (CVE-2015-7566)
It was discovered that a race condition existed when handling heartbeat-
timeout events in the SCTP implementation of the Linux kernel. A remote
attacker could use this to cause a denial of service. (CVE-2015-8767)
It was discovered that a race condition existed in the ioctl handler for
the TTY driver in the Linux kernel. A local attacker could use this to
cause a denial of service (system crash) or expose sensitive information.
(CVE-2016-0723)
Andrey Konovalov discovered that the ALSA USB MIDI driver incorrectly
performed a double-free. A local attacker with physical access could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code with administrative privileges. (CVE-2016-2384)
Ralf Spenneberg discovered that the USB driver for Treo devices in the
Linux kernel did not properly sanity check the endpoints reported by the
device. An attacker with physical access could cause a denial of service
