RHBA-2011:1839 - 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:

• The SNMP daemon (snmpd) did not properly fill a set of watched socket file descriptors. Therefore, the daemon sometimes terminated unexpectedly with the "select: bad file descriptor" error message when more than 32 AgentX subagents connected to snmpd on 32-bit platforms or more than 64 subagents on 64-bit platforms. With this update, snmpd properly clears sets of watched file descriptors and thus it no longer crashes when handling a large number of subagents. (BZ#753766)

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

Solution
