Vulnerability from csaf_redhat - Published: 2026-02-09 20:49 - Updated: 2026-03-27 03:17Summary
Red Hat Security Advisory: Red Hat Web Terminal Operator 1.12.1 release.
Severity
Important
Notes
Topic: Red Hat Web Terminal Operator 1.12.1 has been released.
Details: The Web Terminal provides a way to access a fully in-browser terminal emulator within the OpenShift Console. Command-line tools for interacting with the OpenShift cluster are pre-installed.
Terms of Use: This content is licensed under the Creative Commons Attribution 4.0 International License (https://creativecommons.org/licenses/by/4.0/). If you distribute this content, or a modified version of it, you must provide attribution to Red Hat Inc. and provide a link to the original.
A flaw was found in golang. A remote attacker could exploit this vulnerability by providing a specially crafted certificate during the error string construction process within the `HostnameError.Error()` function. This flaw, caused by unbounded string concatenation, leads to excessive resource consumption. Successful exploitation can result in a denial of service (DoS) for the affected system.
7.5 (High)
Vendor Fix
To start using the Web Terminal Operator, install the Web Terminal Operator from OpenShift OperatorHub on OpenShift Container Platform 4.17 or higher.
