X marks the bug


Security researchers have discovered a critical vulnerability in the X Window system used in Unix and Linux systems. The buffer overflow vulnerability creates a means for hackers to seize root access to vulnerable systems or launch denial of service attacks. So it's just as well that patches are available.

The flaw stems from programming errors within the XRender extension triangle handling code connected with a missing parentheses.
