5865N/A# CVE-2014-2285

5865N/A# https://security-tracker.debian.org/tracker/CVE-2014-2285

5865N/A# The perl_trapd_handler function in perl/TrapReceiver/TrapReceiver.xs in

5865N/A# Net-SNMP 5.7.3.pre3 and earlier, when using certain Perl versions, allows

5865N/A# remote attackers to cause a denial of service (snmptrapd crash) via an empty

5865N/A# community string in an SNMP trap, which triggers a NULL pointer dereference

5865N/A# within the newSVpv function in Perl.

5865N/A#

5865N/A# Fix picked from upstream. Will be available in 5.7.3 and above.
