Synopsis

The remote Debian host is missing a security update.

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

For the oldstable distribution (squeeze), this problem has been fixed in version 2:1.3.3-4+squeeze2.

For the stable distribution (wheezy), this problem has been fixed in version 2:1.5.0-1+deb7u2.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
