Netty (io.netty:netty-handler) versions from 4.2.0.Final through 4.2.16.Final and versions through 4.1.136.Final disable TLS hostname verification on the SslProvider.OPENSSL client path when a plain (non-extended) X509TrustManager is used and Unsafe-based trust-manager wrapping is unavailable (Java 25+). In this configuration the OpenSSL client does not perform hostname verification, allowing a man-in-the-middle attacker to present a certificate issued for a different hostname that is accepted without validation. Fixed in 4.2.17.Final and 4.1.137.Final.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Netty (io.netty:netty-handler) versions from 4.2.0.Final through 4.2.16.Final and versions through     4.1.136.Final disable TLS hostname verification on the SslProvider.OPENSSL client path when a plain (non-     extended) X509TrustManager is used and Unsafe-based trust-manager wrapping is unavailable (Java 25+). In     this configuration the OpenSSL client does not perform hostname verification, allowing a man-in-the-middle     attacker to present a certificate issued for a different hostname that is accepted without validation.
    Fixed in 4.2.17.Final and 4.1.137.Final. (CVE-2026-62243)

Note that Nessus relies on the presence of the package as reported by the vendor.
