mod_cloud_notify_encrypted: Ensure body substring remains valid UTF-8
The `body:sub()` call risks splitting the string in the middle of a
multi-byte UTF-8 sequence. This should have been caught by util.stanza
validation, but that would have caused some havoc, at the very least causing
the notification to not be sent.
There have been no reports of this happening. Likely because this module
isn't widely deployed among users with languages that use many longer UTF-8
sequences.
The util.encodings.utf8.valid() function is O(n) where only the last
sequence really needs to be checked, but it's in C and expected to be fast.

--- labels: - 'Stage-Alpha' - 'Type-S2SAuth' summary: Fingerprint based s2s authentication ... Introduction ============ This module allows you to manually pin certificate fingerprints of remote servers. Details ======= Servers not listed in the configuration are not affected. Configuration ============= After installing and enabling this module, you can put fingerprints of remote servers in your config like this: ``` {.lua} s2s_auth_fingerprint_digest = "sha1" -- This is the default. Other options are "sha256" and "sha512" s2s_trusted_fingerprints = { ["jabber.org"] = "11:C2:3D:87:3F:95:F8:13:F8:CA:81:33:71:36:A7:00:E0:01:95:ED"; ["matthewwild.co.uk"] = { "FD:7F:B2:B9:4C:C4:CB:E2:E7:48:FB:0D:98:11:C7:D8:4D:2A:62:AA"; "CF:F3:EC:43:A9:D5:D1:4D:D4:57:09:55:52:BC:5D:73:06:1A:A1:A0"; }; } -- If you don't want to fall back to dialback, you can list the domains s2s_secure_domains too s2s_secure_domains = { "jabber.org"; } ``` Compatibility ============= ------- -------------- trunk Works 0.9 Works 0.8 Doesn't work ------- --------------
