dsa-5549 advisory.

  - Improper input validation vulnerability on the range header in Apache Software Foundation Apache Traffic
    Server.This issue affects Apache Traffic Server: through 9.2.1. (CVE-2022-47185)

  - Improper Input Validation vulnerability in Apache Software Foundation Apache Traffic Server.This issue
    affects Apache Traffic Server: through 9.2.1. (CVE-2023-33934)

  - Improper Input Validation vulnerability in Apache Traffic Server with malformed HTTP/2 frames.This issue
    affects Apache Traffic Server: from 9.0.0 through 9.2.2. Users are recommended to upgrade to version
    9.2.3, which fixes the issue. (CVE-2023-39456)

  - Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Traffic Server.This
    issue affects Apache Traffic Server: from 8.0.0 through 8.1.8, from 9.0.0 through 9.2.2. Users are
    recommended to upgrade to version 8.1.9 or 9.2.3, which fixes the issue. (CVE-2023-41752)

  - The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation
    can reset many streams quickly, as exploited in the wild in August through October 2023. (CVE-2023-44487)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
