It was reported  that Net-SNMP releases 5.5 through 5.7.2 were vulnerable to a potential remotely-triggerable denial of service attack on the Linux platform, when the ICMP-MIB is in use. Net-SNMP 5.4.x users, and those who do not make use of the ICMP-MIB table objects, are not vulnerable.
This is fixed in git .
