The X Input Method (XIM) client implementation in libX11 has some integer overflows and signed/unsigned comparison issues that can lead to heap corruption when handling malformed messages from an input method.

For Debian 8 jessie, these problems have been fixed in version 2:1.6.2-3+deb8u3.

We recommend that you upgrade your libx11 packages.
