Description Vincent Danen 2014-02-26 17:40:35 UTC
It was reported [1] 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 [2].

Created attachment 868119 [details]
upstream patch to correct the flaw

I don't like sourceforge's web interface to git so this is the actual patch in a useable form.
