Official Description
Array index error in the handle_nsExtendOutput2Table function in agent/mibgroup/agent/extend.c in Net-SNMP 5.7.1 allows remote authenticated users to cause a denial of service (out-of-bounds read and snmpd crash) via an SNMP GET request for an entry not in the extension table.
Technical Analysis
CVE-2012-2141 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
