A flaw was found in Netty. An unsafe reading of the environment file could potentially cause a denial of service. When loaded on a Windows application, Netty attempts to load a file that does not exist. If an attacker creates a large file, the Netty application crashes.
5.5 (Medium)
Vendor Fix
Before applying the update, make sure all previously released errata relevant to your system have been applied. Also, back up your existing installation, including all applications, configuration files, databases and database settings. For details on how to apply this update, refer to: https://access.redhat.com/articles/11258
https://access.redhat.com/errata/RHSA-2025:4552
