Last modified

CVE-2007-4568 is a vulnerability of currently unknown severity. Integer overflow in the build_range function in X.Org X Font Server (xfs) before 1.0.5 allows context-dependent attackers to execute arbitrary code via (1) QueryXBitmaps and (2) QueryXExtents protocol requests with crafted size values, which triggers a heap-based buffer overflow.. EPSS estimates a 3.98% chance of exploitation in the next 30 days.
