Synopsis
The remote CentOS host is missing one or more security updates for cockpit.Description
The remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the cockpit-368-1.el9 build changelog.- A flaw was found in Cockpit. An unauthenticated remote attacker can exploit this vulnerability by initiating and sustaining numerous simultaneous connections to the `cockpit-tls` service. This forces the service to create an unbounded number of detached threads, consuming system resources such as memory and file descriptors. The primary consequence is a denial of service (DoS), leading to degradation or complete unavailability of the Cockpit service for legitimate users. (CVE-2026-91149)
- Automatic update for cockpit-368-1.fc45. ##### **Changelog for cockpit** ``` * Wed Sep 23 2026 Packit <[email protected]> - 368-1 - Limit concurrent connections CVE-2026-91149 - Harden cockpit-ws against trailing slash CVE-2026-91147 - Sanitize URLs from PackageKit CVE-2026-91148 - Interactive file chooser for SSH keys - Bug fixes and translation updates - Resolves RHEL-263070, RHEL-262891, RHEL-253609 for rhel-10.4 - Resolves RHEL-263066 for rhel-9.10 ``` (CVE-2026-91148)
- A flaw was found in `cockpit-ws`. This vulnerability allows a remote, unauthenticated attacker to cause a Denial of Service (DoS) by sending a specially crafted request. When the `WebService.UrlRoot` is configured and a request is made to the exact URL-root prefix without a trailing slash, `cockpit-ws` can terminate unexpectedly. This issue leads to the unavailability of the Cockpit web service.
(CVE-2026-91147)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
