Description:
Dave Aitel has reported a vulnerability in Common Desktop Environment (CDE), which may be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a double-free error in dtlogin when parsing XDMCP (X Display Manager Control Protocol) requests. This can potentially be exploited via a specially crafted XDMCP request to execute arbitrary code on an affected system.
Solution:
Disable XDMCP support in the dtlogin service.
Restricting access to the service based on IP addresses is not a sufficient solution, since the service is connection-less and therefore uses UDP datagrams, where the originating IP easily can be spoofed.
Provided and/or discovered by:
Dave Aitel, Immunity.
