Fedora 28 : libxkbcommon (2018-4295467df0)

medium Nessus Plugin ID 120379

Language:

Synopsis

The remote Fedora host is missing a security update.

Description

libxkbcommon 0.8.2, CVE-2018-15853 to 15864. These fix a number of memory handling issues with xkbcommon. Together with the keymap FD handling in various Wayland compositors (keymaps could be mapped rw and clients could thus replace the content) libxkbcommon's memory issues could serve as attack vector to gain access to another client.

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

Solution

Update the affected libxkbcommon package.
