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-existent 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.

SunOS 5.10: SMA patch.
Date this patch was last updated by Sun : Jun/30/11

The SNMP service did not correctly handle TCP disconnects. Remote subagents could cause a denial of service if they dropped a connection at a specific time.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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

    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.

    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.
