Matthieu Herrb reports:

+
Tobias Stoeckmann from the OpenBSD project has discovered a + number of issues in the way various X client libraries handle + the responses they receive from servers, and has worked with + X.Org's security team to analyze, confirm, and fix these issues. + These issue come in addition to the ones discovered by Ilja van + Sprundel in 2013.
+ +
Most of these issues stem from the client libraries trusting + the server to send correct protocol data, and not verifying + that the values will not overflow or cause other damage. Most + of the time X clients and servers are run by the same user, with + the server more privileged than the clients, so this is not a + problem, but there are scenarios in which a privileged client + can be connected to an unprivileged server, for instance, + connecting a setuid X client (such as a screen lock program) + to a virtual X server (such as Xvfb or Xephyr) which the user + has modified to return invalid data, potentially allowing the + user to escalate their privileges.
