Notes
Title of the patch: Security update for go-sendxmpp
Description of the patch: This update for go-sendxmpp fixes the following issues: Changes in go-sendxmpp: - Update to 0.16.0: Added: * Add Ox support to http-upload. * Add Ox support for private group chats. * Show error cause if joining MUCs failedi (requires go-xmpp >= v0.3.5). Changed: * Fix --ox-delete-nodes. * Fix receiving of 1-1 messages while joined in a MUC. * Use go-sendxmpp + a random ID as fallback MUC alias. * Strip leading "xmpp:" from recipients. * Strip trailing "?join" from MUC JIDs. * Add context for timeouts in stanza handling. * Check ID for disco items reply (requires go-xmpp >= v0.3.6). * Reduce channel buffer size to 1 where only one item will be returned. * Deprecate legacy PGP. * CVE-2026-1229: The CombinedMult function produces an incorrect value (bsc#1265538) Bump circl to 1.6.3 * CVE-2026-39821: Failure to reject ASCII-only Punycode-encoded labels allows for validation bypass and privilege escalation (bsc#1266617) Bump net to 0.56.0 - Update to 0.15.8: * Fix windows build (windows doesn't support syscalls Setgid and Setuid). - Update to 0.15.7: * Fix http-upload with legacy PGP encryption. * Fix reading of environment variables. * Fix a bug in looking up host meta 2. * Try to drop root privileges before connecting to the server. * Fix crash if a config key has no value. * Use a salt for stored FAST token. * Increase scrypt iterations for storing FAST token from 32768 to 65536. * Log a warning when --no-tls-verify or -n is set. - Update to 0.15.6: Added: * New config option allow_plain. Changed: * Explain each configuration option in manpage go-sendxmpp(5). * Improve config parsing robustness. * Update link in manpage as Gitlab calls issues now work items. * Recognize stanza size limit updates after authentication (via go-xmpp >= v0.3.3). * Tell connection target in error message when failing to connect. - Drop tar-scm service and use regular tarball and go_modules - Update to 0.15.5: * Fix SASL SCRAM Downgrade Protection in case of server providing different mechanisms for SASL and SASL2 (requires go-xmpp >0 v0.3.2). - Update to 0.15.4: * http-upload: Manually set content length for HTTP request (fixes issues with certain http modules/proxies). - Update to 0.15.3: * Fix PLAIN authentication for SASL2 (requires go-xmpp >= v0.3.1). - Update to 0.15.2: * Use UUIDv7 instead of UUIDv4 for stanza IDs (requires go-xmpp >= v0.2.19). * Fix stanza syntax error for legacy PGP messages. * Print error if legacy PGP and Ox are requested simultaneously. * Reworked OOB file sending and http-upload to use new functions from go-xmpp library (requires go-xmpp >= v0.3.0). * Try password login if FAST login fails.

For example, ToUnicode(\"xn--example-.com\") incorrectly returns the name \"example.com\" rather than an error. This behavior can lead to privilege escalation in programs using the idna package. For example, a program which performs privilege checks on the ASCII hostname may reject \"example.com\" but permit \"xn--example-.com\". If that program subsequently converts the ASCII hostname to Unicode, it will inadvertently permits access to the Unicode name \"example.com\".",
