Overview

ucs-snmp vulnerability


Details

USN-190-1 fixed a vulnerability in the net-snmp library. It was
discovered that the same problem also affects the ucs-snmp
implementation (which is used by the Cyrus email server).

Original advisory:

A remote Denial of Service has been discovered in the SMNP (Simple
Network Management Protocol) library. If a SNMP agent uses TCP sockets
for communication, a malicious SNMP server could exploit this to crash
the agent. Please note that by default SNMP uses UDP sockets.
