Ubuntu 16.04 LTS / 18.04 LTS : IBus regression (USN-4134-2)

high Nessus Plugin ID 129289

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

USN-4134-1 fixed a vulnerability in IBus. The security fix introduced a regression when being used with Qt applications. This update reverts the security fix pending further investigation.

Simon McVittie discovered that IBus did not enforce appropriate access controls on its private D-Bus socket. A local unprivileged user who discovers the IBus socket address of another user could exploit this to capture the key strokes of the other user.

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.
