                   Red Hat Security Advisory

Synopsis:          Low: net-snmp security update
Advisory ID:       RHSA-2005:373-01
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2005-373.html
Issue date:        2005-09-28
Updated on:        2005-09-28
Product:           Red Hat Enterprise Linux
CVE Names:         CAN-2005-2177 CAN-2005-1740
- ---------------------------------------------------------------------

1. Summary:

Updated net-snmp packages that fix two security issues and various bugs
are now available.

This update has been rated as having low security impact by the Red Hat
Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64

3. Problem description:

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

A denial of service bug was found in the way net-snmp uses network stream
protocols. It is possible for a remote attacker to send a net-snmp agent a
specially crafted packet which will crash the agent. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2005-2177 to this issue.

An insecure temporary file usage bug was found in net-snmp's fixproc
command. It is possible for a local user to modify the content of temporary
files used by fixproc which can lead to arbitrary command execution. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CAN-2005-1740 to this issue.

Additionally the following bugs have been fixed:
 - snmpwalk no longer hangs when a non-existant pid is listed. 
 - snmpd no longer segfaults due to incorrect handling of lmSensors. 
 - an incorrect assignment leading to invalid values in ASN mibs has been
   fixed.
 - on systems running a 64-bit kernel, the values in /proc/net/dev no 
   longer become too large to fit in a 32-bit object. 
 - the net-snmp-devel packages correctly depend on elfutils-libelf-devel.
 - large file systems are correctly handled
 - snmp daemon now reports gigabit Ethernet speeds correctly
 - fixed consistency between IP adresses and hostnames in configuration file

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

4. 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:

https://rhn.redhat.com/help/latest-up2date.pxt

5. Bug IDs fixed (http://bugzilla.redhat.com/):

130252 - net-snmp-devel should depend on elfutils-libelf-devel
152448 - snmpd.conf hostname vs. IP inconsistancy
154455 - 64bit network counters peg instead of wrapping
162907 - CAN-2005-2177 net-snmp denial of service
164639 - CAN-2005-1740 net-snmp insecure temporary file usage
