Description Vincent Danen 2012-09-14 10:50:22 EDT
A Debian bug was filed about ssmtp not checking certificates:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=662960

And it includes a patch to enable checking of server certificates when using TLS:

http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=5;filename=0003-Validate-the-server-certificate-when-using-TLS.patch;att=1;bug=662960

We should include this patch.

Note that this isn't a security _flaw_ because the TLS file in the source tarball clearly states that this feature is missing:


TODO:
* Check server certificate for changes and notify about it.
* Diffrent Certificate and Key file?


This patch would be ideal to have in both Fedora and EPEL ssmtp packages.

Please refer to the SRT bug for this (one of these is a dupe, but using this as the dupe rather than the SRT/CVE bug).
