Fedora Update Notification
FEDORA-2018-11ed8d95e2

Name : libxkbcommon
Product : Fedora 27
Version : 0.8.2
Release : 1.fc27
URL : http://www.x.org
Summary : X.Org X11 XKB parsing library
Description :
libxkbcommon is the X.Org library for compiling XKB maps into formats usable by
the X Server or other display servers.

-------------------------------------------------------------------------------

Update Information:

libxkbcommon 0.8.2, CVE-2018-15853 through 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. The update to 0.8.2 is a lot easier and safer
than backporting all patches, given the number of other fixes not (yet?)
assigned a CVE.
