Ubuntu Security Notice USN-3072-2
August 29, 2016
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
Several security issues were fixed in the kernel.
- linux-ti-omap4: Linux kernel for OMAP4
Kangjie Lu discovered an information leak in the Reliable Datagram Sockets
(RDS) implementation in the Linux kernel. A local attacker could use this
to obtain potentially sensitive information from kernel memory.
Yue Cao et al discovered a flaw in the TCP implementation's handling of
challenge acks in the Linux kernel. A remote attacker could use this to
cause a denial of service (reset connection) or inject content into an TCP
It was discovered that a heap based buffer overflow existed in the USB HID
driver in the Linux kernel. A local attacker could use this cause a denial
of service (system crash) or possibly execute arbitrary code.
The problem can be corrected by updating your system to the following
Ubuntu 12.04 LTS:
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.
