Severity
Important
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 0.17.0: * Add --ox-transfer-private-key to transfer the encrypted private key to PEP to transfer it to other devices (requires go-xmpp >= v0.3.7). * Add --ox-receive-private-key to receive the encrypted private key from PEP. * Add config option no_root_warning. * Add config option no_legacy_pgp_warning. * Also disable legacy PGP when running as root (Ox was already disabled). * Disable pinning for not using PLAIN when running as root. * Add config option ox_trust_mode with settings blind and tofu. * Due to new tofu trust mode for Ox, only one public key per contact is accepted for easier ID handling. * Ox: Check that fingerprint of received key equals the advertised one. * CVE-2026-39821: Failure to reject ASCII-only Punycode-encoded labels allows for validation bypass and privilege escalation (bsc#1266617): Bump net to 0.57.0
