Red Hat Bugzilla – Bug 336101
CVE-2007-4136 ricci is vulnerable to a connect DoS attack
Last modified: 2009-07-03 17:09:56 EDT
The ricci daemon will accept a maximum of 10 active connections. If the
connection limit is reached, new connections will be dropped. ricci only updates
its connection count (after freeing all stale connections) when poll(2) returns
0. If an attacker fills the connection queue, and either keeps sending data or
keeps connecting (or does anything else that'd cause poll() to return non-zero),
ricci will be unable to accept new connections.
This was found during a code audit chasing down a memory leak bug..
