USN-3779-1: Linux kernel vulnerabilities
2 October 2018
Several security issues were fixed in the Linux kernel.
Releases
Packages
- linux - Linux kernel
Details
It was discovered that an integer overflow vulnerability existed in the
Linux kernel when loading an executable to run. A local attacker could use
this to gain administrative privileges. (CVE-2018-14634)
It was discovered that a stack-based buffer overflow existed in the iSCSI
target implementation of the Linux kernel. A remote attacker could use this
to cause a denial of service (system crash). (CVE-2018-14633)
Update instructions
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.
