Debian DSA-4525-1 : ibus - security update

high Nessus Plugin ID 129026

Synopsis

The remote Debian host is missing a security-related update.

Description

Simon McVittie reported a flaw in ibus, the Intelligent Input Bus. Due to a misconfiguration during the setup of the DBus, any unprivileged user could monitor and send method calls to the ibus bus of another user, if able to discover the UNIX socket used by another user connected on a graphical environment. The attacker can take advantage of this flaw to intercept keystrokes of the victim user or modify input related configurations through DBus method calls.

Solution

Upgrade the ibus packages.

For the oldstable distribution (stretch), this problem has been fixed in version 1.5.14-3+deb9u2.

For the stable distribution (buster), this problem has been fixed in version 1.5.19-4+deb10u1.
