Advisory Content (Page 1 of 3)[ 1 ] [ 2 ] [ 3 ]

Description:
A vulnerability has been identified in Xinetd, which can be exploited by malicious people to cause a DoS (Denial of Service) on a vulnerable system.

The vulnerability is caused due to an error in the function "svc_request" when connection attempts to some services are rejected. The problem is that the allocated memory is not always free'd, which results in a memory leak of 144 bytes each time a connection attempt is rejected.

This can be exploited by a malicious person to consume all available memory on a vulnerable server by trying to connect multiple times to a service configured to be run via xinetd.

Successful exploitation requires that the file "xinetd.conf" includes statements that would cause a connection to be rejected.
