What is CVE-2007-4568?

The vulnerability involves an integer overflow in the build_range function of X.Org's X Font Server (xfs) prior to version 1.0.5. Exploitation of this flaw allows context-dependent attackers to execute arbitrary code by sending crafted requests via QueryXBitmaps and QueryXExtents with manipulated size values. This results in a heap-based buffer overflow, potentially compromising the integrity of the affected systems.
