Synopsis

The remote openSUSE host is missing a security update.

Description

The remote openSUSE 16 host has packages installed that are affected by a vulnerability as referenced in the openSUSE- SU-2026:21573-1 advisory.

 Update to version 2.3.14+git0.e23b4c54.

 Security issues fixed:

 - CVE-2026-45784: incorrect sizing of output buffers in `CipherCtxRef::cipher_update_inplace` when used with AES key-wrap-with-padding ciphers can lead to attacker-controlled heap corruption (bsc#1270985).
 - Arbitrary HTTP or HTTPS URLs classified as Office documents based on an attacker-controlled file query parameters are forwarded to Electron applications and allow for code execution through Electron (bsc#1273910).
 - Directory-provided RFC2307 user identifiers accepted without exclusion of systemd's dynamic-user range allows for daemon impersonation and command execution through the task helper (bsc#1273911).
 - Daemon acts on Hello PIN enrollment requests whose identity claims it never cryptographically verifies and allows for local authentication bypass (bsc#1273912).

 Other updates and bugfixes:

 - Version 2.3.14+git0.e23b4c54:
 * fix(`nss`): avoid locked shadow entries
 * fix(`deps`): update libhimmelblau lockfile

 * Fix `cargo-fuzz` install in fuzz CI
 * `cargo vet`
 * Update `ldap3_proto` to 0.7.1
 * Update `openssl`
 - Version 2.3.12:
 * Remove invalid `himmelblau.conf` example info
 * Fix SSHd configuration load order on Fedora/RHEL systems
 * `himmelblau-init-hsm-pin`: don't bind the `hsm-pin` to PCR7
 * `qr-greeter`: support GNOME Shell 50
 * Update `libhimmelblau` to latest version
 * deps(`rust`): bump `tonic` in the `all-cargo-updates` group across 1 directory
