Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

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 that 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 that 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: - The lmSensors are
correctly recognized, snmp deamon no longer segfaults - The larger
swap partition sizes are correctly reported - Querying
hrSWInstalledLastUpdateTime no longer crashes the snmp deamon - Fixed
error building ASN.1 representation - The 64-bit network counters
correctly wrap - Large file systems are correctly handled - Snmptrapd
initscript correctly reads options from its configuration file
/etc/snmp/snmptrapd.options - Snmp deamon no longer crashes when
restarted using the agentX protocol - snmp daemon now reports gigabit
Ethernet speeds correctly - MAC adresses are shown when requested
instead of IP adresses

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