RHBA-2007:0183 - Bug Fix Advisory

Topic

Updated net-snmp packages that fix various bugs are now available.

Description

SNMP (Simple Network Management Protocol) is a protocol used for network
management.

This update includes the following fixes:

• The snmpd daemon initscript stores its pid in /var/run/snmpd instead of

/var/run/snmpd.pid.

• The snmpd daemon log file handling is compatible with logrotate.
• Fixed snmptrapd memory leaks.
• Processor table was added to the list of available MIBs.
• The support for disman event MIB is compiled in by default.
• Fix for snmpd crashes on unacknowledged informs.
• The snmptrapd daemon honors options set in

/etc/sysconfig/snmptrapd.options file.

• The snmpd daemon honors options from /etc/sysconfig/snmpd file
• Fix for snmptrapd segfault when receiving certain traps.
• Better fix for truncating integer values to 32bits.
• Fix for snmpd crash during startup.
• Fix for negative request ids.
• Fix for tcp_wrappers. The communication can be correctly limited.

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

Solution

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

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

If up2date fails to connect to Red Hat Network due to SSL
Certificate Errors, you need to install a version of the
up2date client with an updated certificate. The latest version of
up2date is available from the Red Hat FTP site and may also be
downloaded directly from the RHN website:
