Re: Zimbra for Ubuntu 18.04 ?

The fix is to escape that opening brace that perl is complaining about. diff --git a/src/libexec/zmsyslogsetup b/src/libexec/zmsyslogsetup index 571063e2..840b644b 100755 --- a/src/libexec/zmsyslogsetup +++ b/src/libexec/zmsyslogsetup @@ -187,7 +187,7 @@ sub updateSyslogNG { s/(^log.*f_mailwarn)/#$1...

Re: TLS v 1.3

ZCS does not have support for TLSv1.3 yet. Keep in mind the equivalent of "GA" releases from OpenSSL and OpenJDK, which ZCS depends on, are quite new. Public bugs: ⋅  https://bugzilla.zimbra.com/show_bug.cgi?id=108910 ⋅  https://bugzilla.zimbra.com/show_bug.cgi?id=10903...

Re: ZCS 8.8 upgrade failed with IPv6 enabled

This issue appears to be more fallout from the fix for https://bugzilla.zimbra.com/show_bug.cgi?id=107963 . Also, as mentioned earlier using ipv6only=off more than once seems wrong (per the docs, and noted server behavior. ref: http://nginx.org/en/docs/http/ngx_http_core_module.html#listen ). Diggin...

Re: IOException: Too many open files file leak pipe

This reminds me of https://wiki.zimbra.com/wiki/Performance_Tuning_Guidelines_for_Large_Deployments#Open_File_Descriptors_Limit - although the tweaks to raise limits usually happen on install IIRC. So, maybe somehow those tweaks were never applied or perhaps the server wasn't rebooted to get the cha...

Re: [Solved] HTTP Security Headers

My initial thoughts are that there's likely little (and perhaps no) value to adding headers like this on a HTTP *redirect* (to HTTPS) response. If we were serving up actual content over HTTP (non TLS) then perhaps there's some value. However, using a service such as email over non-TLS protocols is i...

Re: httpoxy

The short answer is, at this point, that there do not appear to be any issues with supported versions of ZCS relating to the vulnerability being referred to as httpoxy.

The short recap, is that we recommend staying up to date on OS and ZCS version and patches, and be sure that you double check for proper controls on your systems (consider comparing your system setup against...

Re: STARTTLS Plaintext Command Injection

Are there any resolutions for this? Yes, upgrade to a current release of Zimbra. Definitely upgrade. There are numerous other security related fixes that you're missing out on if you're still on 8.0.7. You might be interested in keeping an eye on the following: ⋅  https://wiki.zimbra.com/...
