Fedora 27 libxkbcommon Update: Moderate Memory Issues Fixed

fedora
Calendar Grey September 29, 2018
Dist Fedora Esm H88
This patch resolves various memory vulnerabilities in libxkbcommon, bolstering protection against possible threats in Fedora.
libxkbcommon 0.8.2, CVE-2018-15853 through to 15864

Summary

libxkbcommon is the X.Org library for compiling XKB maps into formats usable by

the X Server or other display servers.

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.
