(RHSA-2005:395) net-snmp security update

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
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 that 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:

• 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.
