CVE-2014-2285

Status Candidate

Overview

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.

Mandriva Linux Security Advisory 2015-092

Mandriva Linux Security Advisory 2015-092 - Remotely exploitable denial of service vulnerability in Net-SNMP, in the Linux implementation of the ICMP-MIB, making the SNMP agent vulnerable if it is making use of the ICMP-MIB table objects. Remotely exploitable denial of service vulnerability in Net-SNMP, in snmptrapd, due to how it handles trap requests with an empty community string when the perl handler is enabled. A remote denial-of-service flaw was found in the way snmptrapd handled certain SNMP traps when started with the -OQ option. If an attacker sent an SNMP trap containing a variable with a NULL type where an integer variable type was expected, it would cause snmptrapd to crash.

Red Hat Security Advisory 2014-0322-01 - The net-snmp packages provide various libraries and tools for the Simple Network Management Protocol, including an SNMP library, an extensible agent, tools for requesting or setting information from SNMP agents, tools for generating and handling SNMP traps, a version of the netstat command which uses SNMP, and a Tk/Perl Management Information Base browser. A denial of service flaw was found in the way snmpd, the Net-SNMP daemon, handled subagent timeouts. A remote attacker able to trigger a subagent timeout could use this flaw to cause snmpd to loop infinitely or crash.
