"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.");
