RHEL 4 : net-snmp (RHSA-2005:395)

high Nessus Plugin ID 19988

Synopsis

The remote Red Hat host is missing one or more security updates for net-snmp.

Description

The remote Redhat Enterprise Linux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2005:395 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL net-snmp package based on the guidance in RHSA-2005:395.
