Detailsinfo

A vulnerability, which was classified as problematic, was found in net-snmp 5.7.3 (Network Management Software). Affected is the function newSVpv of the component PERL Handler. The manipulation as part of a Community String leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on availability. CVE summarizes:

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.

The weakness was disclosed 03/05/2014 as CVE request for two net-snmp remote DoS flaws as confirmed mailinglist post (oss-sec). The advisory is available at seclists.org. The public release has been coordinated in cooperation with the vendor. This vulnerability is traded as CVE-2014-2285 since 03/05/2014. The exploitability is told to be easy. 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.
