high Nessus Plugin ID 374756

Synopsis

The remote openSUSE host is missing one or more security updates.

Description

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:22189-1 advisory.

 Changes in shadowsocks-rust:

 - Fix SELinux denial (name_connect) when forwarding outbound TCP traffic (boo#1284975)

 - Fix: Unable to bind ports below 1024 with SELinux enabled (boo#1284025)

 - Update version to 1.25.0
 * Allow chaining ssserver to another SOCKS5/HTTP/HTTPS proxy
 * Expose user_key() on CryptoStream and ProxyServerStream, lets callers identify which multi-user identity was authenticated after an AEAD-2022 handshake
 * EIH (Extended Identity Header) support
 * local-http: Support HTTP Basic auth
 * service: Outbound UDP relay through SOCKS5-only chains. UDP traffic can now be relayed through proxy chains when all hops are SOCKS5. Chains containing HTTP/HTTPS hops will emit a startup warning and UDP traffic will bypass the chain.
 * socket2::Socket with socket2::SockRef
 * Fix bugs
 * CVE-2026-25541 and boo#1274441
 * CVE-2026-93599, CVE-2026-93602, CVE-2026-93601, CVE-2026-93600 and boo#1282208
 * CVE-2026-25541 and boo#1274441

 * Fix some issues (CVE-2025-3416, boo#1242615)
 - Update vendor, fix boo#1215658 and CVE-2023-42811

 Changes in shadowsocks-libev:

 - Fix SELinux denial (name_connect) when forwarding outbound TCP traffic (boo#1284975)

 - Fix build for Leap 16.1+: switch BuildRequires from mbedtls-devel to mbedtls-3-devel Tumbleweed, don't do this work on Leap 16

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
