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.

Uncontrolled Recursion vulnerability in Apache Thrift go bindings.



Both Go transports satisfy a read out of a buffered frame and, when that frame yields no payload bytes, read the next frame and call `Read` again instead of looping. A peer produces such a frame for 4 bytes in `TFramedTransport` (a declared size of zero) or 18 bytes in `THeaderTransport` (a header block that fills the frame), so nothing bounds the depth. The Go stack limit is reached as a `fatal error`, which `recover()` cannot catch, so the whole process dies.



This issue affects Apache Thrift: before 0.25.0.



Users are recommended to upgrade to version 0.25.0, which fixes the issue.
