RHBA-2009:1437 - net-snmp bug fix update

Synopsis

net-snmp bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated net-snmp packages that resolve several issues are now available.

Description

The Simple Network Management Protocol (SNMP) is a protocol used for network management. The net-snmp packages include various SNMP tools:an extensible agent, an SNMP library, 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 MIB browser.

These updated net-snmp packages provide fixes for the following bugs:

  • snmpd, the SNMP daemon, did not expect the packet counters in the /proc/net/snmp and /proc/net/snmp6 directories to be 64-bit on 64-bit systems. When these counters exceeded 32 bits in size, which would occur when the Linux kernel sent or received greater than 4,294,967,296 (2^32) packets, then the snmpd daemon would terminate abnormally. With this update, the snmpd daemon no longer crashes when it encounters a packet counter in the directories listed above that is greater than 32 bits in size, thus resolving the issue. (BZ#516183)

  • snmpd, the SNMP daemon, contained several memory leaks in the ipNetToMediaTable module. These leaks caused snmpd to leak memory relatively slowly, but at a rate which could cause problems on machines with multi-month uptimes. These memory leaks have been plugged in these updated packages so that snmpd no longer leaks memory slowly. (BZ#517041)

All users of net-snmp are advised to upgrade to these updated packages, which resolve these issues.

Solution

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.
