Re: ZBUG-2592: Completely disable offline mode #868

Browsers (specifically Chrome) had already phased out the technology used by Offline mode, see viewtopic.php?f=15&t=68669

Re: How To Use cURL With Zimbra's New Support Vault

Hi Mark

I tried this, but I get an error "password login forbidden" when using curl this way. I can only access the vault with a browser (with the same password...), not with WebDAV.
Is this something Zimbra support needs to enable per location / per user?

Re: BUG: Cannot set zimbraHttpCompressionEnabled to FALSE in zimbra 9 and 10

Yes indeed. That's why I'm subscribed to (some of) their github repo's. But the proprietary parts are not visible there of course.

Re: Zimbra 10.0.7 FIPS manage ciphers offered?

You can easily disable all DHE ciphers, just set zimbraSSLDHParam to an empty value: zmprov mcf zimbraSSLDHParam '' (that's an empty value between quotes). Btw, DHE ciphers are not vulnerable or "weak" in a cryptographic sense (when using a strong group), and FIPS mode will not disable the...

Re: Zimbra suddently extremely slow, multiples java process eat more than 100% Cpu, bug or compromized server?

From time to time we have "runaway threads" that consume 100% CPU, a zmmailboxdctl restart "fixes" that (until it comes back).
Over the years we have had several exchanges with support about this, but so far no root cause has been identified.

Re: LDAP do not start as zimbra but start as root.

Do you have zimbra-ldap-patch installed on your LDAP server(s)? Traditionally slapd was started as root (via sudo) to bind on port 389, and then dropped privileges to the zimbra user. This was changed some time ago to be started as zimbra, but with "cap_net_bind" capability to allow to bin...

Re: New CPIO vulnerability (CVE-2023-7216). Zimbra affected?

No need for all this trickery, merely having cpio installed on your system doesn't make it vulnerable, only amavisd using it to extract untrusted input.
If you're on Zimbra 8.8.15 P40 / 9.0.0 P33 / 10.0.1 or newer, amavisd no longer uses cpio, even if pax is missing.

Re: New CPIO vulnerability (CVE-2023-7216). Zimbra affected?

Removing cpio will break generation of initramfs on Red Hat based Linux distributions. This has been warned for on this forum before.

amavisd not using cpio anymore should be sufficient.
