Red Hat Security Advisory
Synopsis: Moderate: net-snmp security update
Advisory ID: RHSA-2014:0322-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-0322.html
Issue date: 2014-03-24
CVE Names: CVE-2012-6151 CVE-2014-2285
=====================================================================
1. Summary:
Updated net-snmp packages that fix two security issues are now available
for Red Hat Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having Moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.
2. Relevant releases/architectures:
RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
3. Description:
The net-snmp packages provide various libraries and tools for the Simple
Network Management Protocol (SNMP), including an SNMP library, an
extensible agent, tools for requesting or setting information from SNMP
agents, tools for generating and handling SNMP traps, a version of the
netstat command which uses SNMP, and a Tk/Perl Management Information Base
(MIB) browser.
A denial of service flaw was found in the way snmpd, the Net-SNMP daemon,
handled subagent timeouts. A remote attacker able to trigger a subagent
timeout could use this flaw to cause snmpd to loop infinitely or crash.
(CVE-2012-6151)
A denial of service flaw was found in the way the snmptrapd service, which
receives and logs SNMP trap messages, handled SNMP trap requests with an
empty community string when the Perl handler (provided by the net-snmp-perl
package) was enabled. A remote attacker could use this flaw to crash
snmptrapd by sending a trap request with an empty community string.
(CVE-2014-2285)
All net-snmp users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. After installing this
update, the snmpd and snmptrapd services will be restarted automatically.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
