Developer androsyn just announced the availability of ircd-ratbox 2.2.9, a new release in their stable branch – shortly after the release of a new version in their testing branch.
Upgrading is strongly advised since this release fixes 2 crashbugs that can be triggered by users.
The functions that potentially can lead to a crash of the IRC daemon are said to be “/quote HELP” and “/links”, however the exact commands are not mentioned in the announcement – we will update this post once more details are known.
The downloads to the updated IRCd can be obtained here.
[Update]: The testing branch seems to be affected too by one of these bugs and has been updated to version 3.0.6.
