Title: Apache Traffic Server Stack-based Buffer Overflow Vulnerability
Overview:

Apache Traffic Server copies the client Host header into a fixed-size stack buffer without a bound during redirect handling so an over-long Host header overflows the stack when redirect following is enabled. This issue affects Apache Traffic Server: from 8.0.0 through 8.1.9 from 9.0.0 through 9.2.14 from 10.0.0 through 10.1.3. Users are recommended to upgrade to version 9.2.15 or 10.1.4 which fix the issue.
