Description Guilherme de Almeida Suckevicz 2026-07-29 19:55:28 UTC

Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

The Apache Traffic Server multiplexer plugin overruns its chunk-decode buffer on upstream input, enabling denial of service.

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.

Comment 1 Jered Floyd 2026-08-13 02:11:38 UTC

Fixed in 9.2.15/10.1.4 but apparently Bodhi has a search limit of 20 bugs so it didn't auto-close.
