sol17315: SNMP vulnerability CVE-2014-3565 

Security Advisory

Original Publication Date: 09/28/2015

Description

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. (CVE-2014-3565)

Impact

The snmpdtrapd process may stop responding if a specially crafted SNMP trap
is received.  BIG-IP, Enterprise Manager, and BIG-IQ systems do not use
the included snmptrapd binary in any supported configuration. On Traffix
systems, the management station will be unable to search the splunk database
for traps that occurred while snmptrapd was down.

Status

F5 Product Development has assigned ID 545322 (BIG-IP), ID 545369 (BIG-IQ),
and ID 545370 (Enterprise Manager), and has evaluated the currently
supported releases for potential vulnerability.

To determine if your release is known to be vulnerable, the components
or features that are affected by the vulnerability, and for information
about releases or hotfixes that address the vulnerability, refer to the
following table:

Recommended Action

If the previous table lists a version in the Versions known to be not
vulnerable column, you can eliminate this vulnerability by upgrading to
the listed version. If the listed version is older than the version you
are currently running, or if the table does not list any version in the
column, then no upgrade candidate currently exists.

F5 responds to vulnerabilities in accordance with the Severity values
published in the previous table. The Severity values and other security
vulnerability parameters are defined in SOL4602: Overview of the F5 security
vulnerability response policy.

To mitigate this vulnerability, you can avoid starting the snmptrapd process.
Additionally, you should only permit management access over a secure network
and limit shell access to only trusted users. For more information about
securing access to BIG-IP and Enterprise Manager systems, refer to SOL13309:
Restricting access to the Configuration utility by source IP address (11.x)
and SOL13092: Overview of securing access to the BIG-IP system.

Impact of action: None
