Subject: Exim security update
Date: Thu, 3 Mar 2016 20:44:17 -0500	[thread overview]
Message-ID: <20160304014417.GA31979@jasmine> (raw)

I just updated Exim from 4.86 to 4.86.2, fixing CVE-2016-1531 [0].

"All installations having Exim set-uid root and using 'perl_startup' are
vulnerable to a local privilege escalation. Any user who can start an
instance of Exim (and this is normally *any* user) can gain root
privileges. If you do not use 'perl_startup' you *should* be safe." [1]

According to upstream, the changes may break existing installations.
Please read their announcement [1] for more details.
