Heads up: important UnrealIRCd hot-fix and release on Saturday (Dec 16, 2023)

[Bram M. <sy...@un...>]

This is a 48+ hours heads up, so UnrealIRCd admins know they should be 
around to patch their server next Saturday:

Internally we discovered a serious issue in UnrealIRCd. In a common 
configuration scenario, a regular user can cause UnrealIRCd to crash, 
which results in all users being disconnected from the server. This 
issue is present in all recent UnrealIRCd releases (the latest 6.1.3, 
but also older ones are affected). At the moment, the risk seems limited 
to a crash only, at least on all tested commonly used Linux variants.

A fixed version, UnrealIRCd 6.1.4, will be released on _*Saturday, 
December 16, 2023, at 16:00 GMT
*_At the same date/time we will also release a "hot patch" so *NIX users 
can fix the issue without restart.

When the fix comes out next Saturday, we suggest admins on *NIX to apply 
the patch immediately (which is possible without downtime and only takes 
a minute) or to upgrade quickly to UnrealIRCd 6.1.4 (e.g. when on 
Windows or if you just feel like upgrading). This is also the reason for 
sending out this pre-announcement with an exact date and time. This way 
people can be "ready" and fix things immediately, minimizing the time 
for bad people potentially crashing IRC servers.

Please understand that until the release at Saturday we cannot provide 
any further information.
