Exploitation vector: Network

Exploit availability: No

Vulnerable software:

Server applications / Remote management servers, RDP, SSH

Vendor: net-snmp.sourceforge.net

Description

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

snmplib/mib.c in net-snmp 5.7.0 and earlier, when the -OQ option is used, allows remote attackers to cause a denial of service (snmptrapd crash) via a crafted SNMP trap message, which triggers a conversion to the variable type designated in the MIB file, as demonstrated by a NULL type in an ifMtu trap message.

Mitigation
Install update from vendor's website.

Vulnerable software versions

Net-snmp: 5.7.0
