FreeBSD : net-mgmt/net-snmp -- Remote Code Execution (snmptrapd) (e2cd20fd-eb10-11f0-a1c0-0050569f0b83)

critical Nessus Plugin ID 281911

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the e2cd20fd-eb10-11f0-a1c0-0050569f0b83 advisory.

 net-snmp development team reports:
 A specially crafted packet to an net-snmp snmptrapd daemon can cause a buffer overflow and the daemon to crash.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
