Ubuntu 14.04 LTS : libx11, libxrender vulnerability (USN-2568-1)

critical Nessus Plugin ID 82766

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

Abhishek Arya discovered that libX11 incorrectly handled memory in the MakeBigReq macro. A remote attacker could use this issue to cause applications to crash, resulting in a denial of service, or possibly execute arbitrary code.

In addition, following the macro fix in libx11, a number of other packages have also been rebuilt as security updates including libxrender, libxext, libxi, libxfixes, libxrandr, libsdl1.2, libxv, libxp, and xserver-xorg-video-vmware.

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

Solution

Update the affected libxrender-dev, libxrender1 and / or libxrender1-udeb packages.
