Name of the Vulnerable Software and Affected Versions PTnet ircd versions 1.5 through 1.6

Description The issue allows remote attackers to cause a denial of service, specifically memory exhaustion that triggers a daemon restart. This is achieved by sending a large number of requests to join a "charmed channel". The affected channels include those named like PTnet, #PTnoticias, and #*.log, which causes ircd to open the channel even without valid users.

Recommendations For PTnet ircd versions 1.5 through 1.6, consider restricting access to charmed channels as a temporary workaround until a patch is available. Avoid allowing a large number of requests to join these channels to minimize the risk of exploitation.
