Weaknesses
CWE-119

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.

Affected configurations

• x x.org x11 6.0 • x x.org x11 6.1 • x x.org x11 6.3 • x x.org x11 6.4 • x x.org x11 6.5.1 • x x.org x11 6.6 • xfree86 xfree86 (<= 3.3.2)
