Netty, an asynchronous, event-driven network application framework, has a vulnerability in versions up to and including 4.1.118.Final. An unsafe reading of environment file could potentially cause a denial of service in Netty. When loaded on an Windows application, Netty attempts to load a file that does not exist. If an attacker creates such a large file, the Netty application crash. A similar issue was previously reported as CVE-2024-47535. This issue was fixed, but the fix was incomplete in that null-bytes were not counted against the input limit. Commit d1fbda62d3a47835d3fb35db8bd42ecc205a5386 contains an updated fix.

The remote Redhat Enterprise Linux 8 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2025:3357 advisory.

    Red Hat JBoss Enterprise Application Platform 8 is a platform for Java applications based on the WildFly     application runtime.

    This asynchronous patch is an update for Red Hat JBoss Enterprise Application Platform 8.0. See Release     Notes for information about the most     significant bug fixes and enhancements included in this release.

    Security Fix(es):

    * org.jboss.narayana-narayana-all: deadlock via multiple join requests sent to LRA Coordinator [eap-8.0.z]     (CVE-2024-8447)

    * io.netty/netty: Denial of Service attack on windows app using Netty [eap-8.0.z] (CVE-2024-47535)

    * io.netty/netty-handler: SslHandler doesn't correctly validate packets which can lead to native crash     when using native SSLEngine [eap-8.0.z] (CVE-2025-24970)

    * netty-common: Denial of Service attack on windows app using Netty [eap-8.0.z] (CVE-2025-25193)
