Ubuntu 18.10 : linux, linux-aws, linux-gcp, linux-kvm, linux-raspi2 vulnerability (USN-4006-1)

low Nessus Plugin ID 125722

Language:

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Federico Manuel Bento discovered that the Linux kernel did not properly apply Address Space Layout Randomization (ASLR) in some situations for setuid a.out binaries. A local attacker could use this to improve the chances of exploiting an existing vulnerability in a setuid a.out binary.

As a hardening measure, this update disables a.out support.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
