Researchers have discovered a critical vulnerability in the X Window system used by *nix systems. A buffer overflow exists that can allow remote attackers access to systems.
The flaw stems from programming errors within the XRender extension triangle handling code connected with a missing parentheses. “This can be exploited by a client that is authorised to connect to the X server to cause a buffer overflow,” security notification firm Secunia explains.
Patches are available.
