How to fix?

Upgrade Debian:unstable net-snmp to version 5.7.2.1~dfsg-3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream net-snmp package and not the net-snmp package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

The perl_trapd_handler function in perl/TrapReceiver/TrapReceiver.xs in Net-SNMP 5.7.3.pre3 and earlier, when using certain Perl versions, allows remote attackers to cause a denial of service (snmptrapd crash) via an empty community string in an SNMP trap, which triggers a NULL pointer dereference within the newSVpv function in Perl.
