Title: X.Org XRender Extension Buffer Overflow Vulnerability
Severity: CRITICAL
Description:
The X.Org X Windows System is a windows server for Unix, Linux, and variants. It is freely available and distributed publicly.
The X.Org X window system is prone to a buffer-overflow vulnerability.
The problem occurs due to a typo in 'render/mitri.c', the X render extension, causing a miscalulation in the size of a buffer.
An attacker can exploit this issue to execute arbitrary code with elevated privileges. This may facilitate a compromise of the affected computer.
