Description

Abhishek Arya discovered a buffer overflow in the MakeBigReq macro provided by libx11, which could result in denial of service or the execution of arbitrary code.

Several other xorg packages (e.g. libxrender) will be recompiled against the fixed package after the release of this update. For detailed information on the status of recompiled packages please refer to the Debian Security Tracker at https://security-tracker.debian.org/tracker/CVE-2013-7439 .
