X.Org and XFree86 X server DBE ProcDbeSwapBuffers() integer overflow

xorg-xserver-dbe-swap-overflow (31379) The risk level is classified as HighHigh Risk

Description:

X.Org and XFree86 X server could allow a local attacker to execute arbitrary code on the system with elevated privileges, caused by an integer overflow in the ProcDbeSwapBuffers() function in the DBE extension. A local attacker with privileges to send commands to the X Server could exploit this vulnerability using a specially-crafted X protocol request to corrupt memory and execute arbitrary code on the system with the privileges of the X server.
