Detail

Product: Solaris 9 Operating System, Solaris 10 Operating System, Solaris 8 Operating System

There exists multiple security vulnerabilities within the handlers for the QueryXBitmaps and QueryXExtents protocol requests for the X Font Server, xfs(1), included with Solaris. These vulnerabilities may allow a local or remote unprivileged user the ability to execute arbitrary code with the privileges of the X font server. The X font server runs as the unprivileged user "nobody" (uid 60001) on Solaris. These vulnerabilities may allow also allow users to consume all available memory on a system resulting in a Denial of Service (DoS).

These issues are also referenced in the following documents:
