Description

A security vulnerability has been found in Net-SNMP releases that could allow a denial of service attack against Net-SNMP agent's which have opened a stream based protocol (EG, TCP but not UDP; it should be noted that Net-SNMP does not by default open a TCP port).

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
