squid -- SNMP module denial-of-service vulnerability


The Squid-2.5 patches page notes:

If a certain malformed SNMP request is received squid restarts with a Segmentation Fault error.

This only affects squid installations where SNMP is explicitly enabled via "make config". As a workaround, SNMP can be disabled by defining "snmp_port 0" in squid.conf.
