Overview

CVE-2012-1699 is a low-severity vulnerability affecting x x.org_x11. It was published on December 21, 2012 and has a CVSS 2.0 base score of 3.6 (LOW).

This vulnerability has a CVSS 2.0 base score of 3.6, rated LOW. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

The ProcSetEventMask function in difs/events.c in the xfs font server for X.Org X11R6 through X11R6.6 and XFree86 before 3.3.3 calls the SendErrToClient function with a mask value instead of a pointer, which allows local users to cause a denial of service (memory corruption and crash) or obtain potentially sensitive information from memory via a SetEventMask request that triggers an invalid pointer dereference.

Remediation

Check the references section for vendor advisories and patches from x. Update x.org_x11 to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
