RHBA-2013:1150 - net-snmp bug fix update

Synopsis

net-snmp bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated net-snmp packages that fix one bug are now available for Red Hat Enterprise Linux 6.

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.

This update fixes the following bug:

• When an AgentX subagent disconnected from the SNMP daemon (snmpd), the daemon did not properly check that there were no active requests queued in the subagent and destroyed the session. Consequently, the session was referenced by snmpd later when processing queued requests and because it was already destroyed, snmpd terminated unexpectedly with a segmentation fault or looped indefinitely. This update adds several checks to prevent the destruction of sessions with active requests, and snmpd no longer crashes in the described scenario. (BZ#993579)

Users of net-snmp are advised to upgrade to these updated packages, which fix this bug.
