USN-3082-2: Linux kernel (OMAP4) vulnerability
19 September 2016
The system could be made to run programs as an administrator.
- linux-ti-omap4 - Linux kernel for OMAP4
Chiachih Wu, Yuan-Tsung Lo, and Xuxian Jiang discovered that the legacy ABI
for ARM (OABI) had incomplete access checks for epoll_wait(2) and
semtimedop(2). A local attacker could use this to possibly execute
The problem can be corrected by updating your system to the following package versions:
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.
