Did a quick merge of a testing branch into main for my #gmail API based MTA, then heading out to lunch and shopping.
Totally should have done a quick test, as no email is arriving, so I assume #exim is busy queuing it while the MTA throws errors.
Bad ScottE. Now I have to login again when we get home, rather than just making a drink and relaxing. Grrr.

We are very close to a new OpenBSD release. "You Have Installed OpenBSD. Now For The Daily Tasks." https://nxdomain.no/~peter/openbsd_installed_now_for_the_daily_tasks.html can help you prepare for the upgrade.
If you are using exim as your MTA (or any other non-base system MTA), "OpenSMTPD Is The Mail Server For The Future" https://nxdomain.no/~peter/time_for_opensmtpd.html contains useful pointers for a better mail future.

Another day, another critical Exim vulnerability. CVE-2026-45185 is a use-after-free (UAF) flaw, dubbed "Dead.Letter," that grants unauthenticated remote code execution on affected mail servers. XBOW researcher Federico Kirschbaum uncovered the bug, leading to a swift patch in Exim 4.99.3. Don't delay: update your internet-exposed Exim instances, especially if running GnuTLS on Ubuntu/Debian. This…

Exim Flaw Exposes Servers to Remote Code Execution
A critical flaw in Exim, tracked as CVE-2026-45185, leaves servers vulnerable to remote code execution if they're running specific builds, but thankfully, a remediation was published in Exim version 4.99.3. This vulnerability is triggered during TLS shutdown while handling certain SMTP traffic, allowing attackers to exploit it.

Is there some "test kit" for #exim for mail deliveries, i.e. I have a bunch of mails and want to make sure they get correctly accepted (or refused)?

🚨 CVE-2026-45185 (Dead.Letter)
Exim before 4.99.3, in certain GnuTLS configurations, has a remotely reachable use-after-free in the BDAT body parsing path. It is triggered when a client sends a TLS close_notify mid-body during a CHUNKING transfer, followed by a final cleartext byte on the same TCP connection. This can lead to heap corruption. An unauthenticated network attacker exploiting this vulnerability could execute arbitrary code.

🚀 Ah, another day, another #CVE nobody asked for. Humans vs. #AI in a race to exploit #Exim, because *obviously* that's what we need—Skynet learning to hack email servers. 😂 But hey, at least the buzzwords and pentest pitches are here to save us from the tedium of actual #security work. 📉
