Package: irssi
Version: 1.2.0-2.1
Severity: normal

Dear Maintainer,

Today, I ran across a problem in irssi - for me, it manifested as /reload
causing my SASL connections to fail auth on (re)connects until I restarted
irssi.

The problem turns out to be a use-after-free in the SASL handling code; the
fix[1] is in 1.2.1 and newer, but it'd be nice if people using buster
weren't stuck with this until they upgraded.

(Nevermind the slightly off Version string; I quickly shoved the patch from
1058 into the package and rebuilt it to confirm the problem went away.)
