There is a vulnerability in the way Sun Solaris handles invalid X Display Manager Control Protocol (XDMCP) requests. Exploitation of this vulnerability could allow an attacker to cause the X Display Manager (XDM) to crash.
The X Display Manager (xdm(1)) is responsible for managing collections of X displays from local or remote servers using the X Display Manager Control Protocol (XDMCP). The Sun Solaris X Display Manager contains a denial-of-service vulnerability that could be triggered by an invalid XDMCP packet.
A remote attacker with the ability to send XDMCP packets to a vulnerable system could cause the X Display Manager to crash.
Sun has issued an advisory which addresses this issue. For more information on patches available for your system, please refer to Sun Security Alert 57619.
