A buffer overflow in the XRender extension potentially allows any X.Org user to execute arbitrary code with elevated privileges.

2.  Impact Information


X.Org is X.Org Foundation's public implementation of the X Window System.


X.Org miscalculates the size of a buffer in the XRender extension.


An X.Org user could exploit this issue to make the X server execute arbitrary code with elevated privileges.
