Hi, Another serious bug has been found in Exim, which is installed by default on Debian and some other Linux distributions: https://seclists.org/oss-sec/2019/q3/253 The impact is remote execution as an unprivileged user, although it cannot be ruled out that there might be other routes to the same code running in a privileged context. If your distribution is still under security support then I expect they will push out new packages in the next few days. If not then you will need to upgrade it or rebuild the package. It's quite a simple fix. There's been no embargo this time, so attacks could be out in the wild already. Cheers, Andy -- https://bitfolk.com/ -- No-nonsense VPS hosting
