  - The AgentX subagent in Net-SNMP before 5.4.4 allows     remote attackers to cause a denial of service (hang) by     sending a multi-object request with an Object ID (OID)     containing more subids than previous requests, a     different vulnerability than CVE-2012-6151.
    (CVE-2014-2310)

The remote host is affected by the vulnerability described in GLSA-201409-02 (Net-SNMP: Denial of Service)

    Multiple vulnerabilities have been discovered in Net-SNMP. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could create a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

Ken Farnen discovered that Net-SNMP incorrectly handled AgentX timeouts. A remote attacker could use this issue to cause the server to crash or to hang, resulting in a denial of service. (CVE-2012-6151)

It was discovered that the Net-SNMP ICMP-MIB incorrectly validated input. A remote attacker could use this issue to cause the server to crash, resulting in a denial of service. This issue only affected Ubuntu 13.10. (CVE-2014-2284)

Viliam Pucik discovered that the Net-SNMP perl trap handler incorrectly handled NULL arguments. A remote attacker could use this issue to cause the server to crash, resulting in a denial of service.
(CVE-2014-2285)

It was discovered that Net-SNMP incorrectly handled AgentX multi-object requests. A remote attacker could use this issue to cause the server to hang, resulting in a denial of service. This issue only affected Ubuntu 10.04 LTS, Ubuntu 12.04 LTS and Ubuntu 12.10.
(CVE-2014-2310).

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.

A buffer overflow flaw was found in the way the decode_icmp_msg() function in the ICMP-MIB implementation processed Internet Control Message Protocol (ICMP) message statistics reported in the /proc/net/snmp file. A remote attacker could send a message for each ICMP message type, which could potentially cause the snmpd service to crash when processing the /proc/net/snmp file. (CVE-2014-2284)

A denial of service flaw was found in the way snmpd, the Net-SNMP daemon, handled subagent timeouts. A remote attacker able to trigger a subagent timeout could use this flaw to cause snmpd to loop infinitely or crash. (CVE-2012-6151)

A denial of service flaw was found in the way the snmptrapd service, which receives and logs SNMP trap messages, handled SNMP trap requests with an empty community string when the Perl handler (provided by the net-snmp- perl package) was enabled. A remote attacker could use this flaw to crash snmptrapd by sending a trap request with an empty community string. (CVE-2014-2285)

After installing this update, the snmpd and snmptrapd services will be restarted automatically.

Updated net-snmp packages that fix two security issues are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The net-snmp packages provide various libraries and tools for the Simple Network Management Protocol (SNMP), including an SNMP library, an extensible agent, tools for requesting or setting information from SNMP agents, tools for generating and handling SNMP traps, a version of the netstat command which uses SNMP, and a Tk/Perl Management Information Base (MIB) browser.

A remote attacker could use this flaw to crash snmptrapd by sending a trap request with an empty community string. (CVE-2014-2285)

All net-snmp users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, the snmpd and snmptrapd services will be restarted automatically.

Updated net-snmp packages fix security vulnerability :

Net-SNMP 5.7.1 and earlier, when AgentX is registering to handle a MIB and processing GETNEXT requests, allows remote attackers to cause a denial of service (crash or infinite loop, CPU consumption, and hang) by causing the AgentX subagent to timeout (CVE-2012-6151).

This update also fixes two other minor issues: IPADDRESS size in python-netsnmp on 64-bit systems and adding btrfs support to hrFSTable.

This update fixes CVE-2012-6151 :

  - snmpd crashes/hangs when AgentX subagent times-out
