Vulnerability Assessment Summary
Check for the version of the net packages

Detailed Explanation for this Vulnerability Assessment

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.

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
CVE-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 CVE-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.
