The X Server was updated to fix 1 security issues and 4 bugs:
Security issues: - CVE-2015-3418: Fixed a regression introduced by CVE-2014-8092 in PutImage that caused crashes when called with 0 height (bnc#928520).
Bugs fixed: - Xephyr: Don't crash when no command line argument is specified The DDX specific command line parsing function only gets called if command line arguments are present. Therefore this function is not suitable to initialize mandatory global variables. Replace main() instead. (bnc#925022) - Xephyr: Print default server display number if none is specified (bnc#925022) - Xephyr: Fix broken image when endianess of client machine and host-Xserver differ The image is created in the native byte order of the machine Xephyr is rendered on however drawn in the image byte order of the Xephyr server. Correct byte order in the xcbimaget structure and convert to native before updating the window. If depths of Xephyr and host server differ this is already taken care of by the depth conversion routine. (bnc#923229). - Xephyr: Fix compile when debugging is enabled (bnc#925021) - Xephyr: Fix screen image draw for the non-Glamor & non-XHSM case xcbimageput() prints the entire image, therefore don't use an offset. (bnc#925019)
