A vulnerability was found in net-snmp (Network Management Software). It has been classified as problematic. Affected is an unknown part of the component SNMP Trap Processor. The manipulation of the argument -OQ with an unknown input leads to a denial of service vulnerability. CWE is classifying the issue as CWE-399. This is going to have an impact on availability.

It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are known, but there is no available exploit. The advisory points out:

When -OQ command line argument is used, variable formatter preffers the type of the varible parsed from a MIB file instead of checking type of the variable as parsed from SNMP message. This can lead to crashes when incoming packets contains a variable with NULL type, while the MIB says the variable should be non-NULL, like Integer. The formatter then tries to interpret the NULL (from packet) as Integer (from MIB file).
