Description Martin Prpič 2015-10-13 08:03:40 UTC 
A flaw was discovered in ircd-ratbox and its derivatives:

Elemental-IRCd is an Internet Relay Chat (IRC / RFC 1459) daemon intended for stable, secure deployments for both private and public-facing users. It provides quick messaging across servers, even when deployed on a global scale. One of the recent goals of the project has been to limit memory leaks and test functionality to ensure quality for all users.

While looking for resource leaks and other things to test inside Elemental-IRCd git master, we stumbled on an unfortunate programming error in how the MONITOR command was handled that can lead to a system out-of-memory event if an attacker hammers at the MONITOR command over and over.
