Name of the Vulnerable Software and Affected Versions IRCD-Hybrid (aka Hybrid2 IRC Services) versions 1.9.2 through 1.9.4

Description The issue allows remote attackers to cause a denial of service, resulting in a daemon crash. This can be achieved by sending a private message to the MemoServ service with the content ":help t".

Recommendations For versions 1.9.2 through 1.9.4, consider restricting access to the MemoServ service until a fix is available. As a temporary workaround, avoid processing private messages with the ":help t" content to prevent daemon crashes.
