NVD Description

Note: Versions mentioned in the description apply only to the upstream capnproto-devel package and not the capnproto-devel package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

Cap'n Proto is a data interchange format and capability-based RPC system. Prior to 1.4.0, a negative Content-Length value was converted to unsigned, treating it as an impossibly large length instead. In theory, this bug could enable HTTP request/response smuggling. This vulnerability is fixed in 1.4.0.
