Mancha discovered a vulnerability in rsyslog, a system for log processing. This vulnerability is an integer overflow that can be triggered by malformed messages to a server, if this one accepts data from untrusted sources, provoking message loss, denial of service and, potentially, remote code execution.
This vulnerability can be seen as an incomplete fix of CVE-2014-3634 (DSA 3040-1).
