| Doc Text: |
Cause:
Net-SNMP did not check that incoming SNMP messages are encoded properly and may have read past the receiving buffer size when parsing a message with invalid size of integer filed in the message.
Consequence:
snmptrapd, the SNMP trap processing daemon, crashed on incoming malformed message.
Fix:
We enhanced the checks of incoming messages.
Result:
snmptrapd no longer crashes when parsing incoming message with invalid integer sizes.
