New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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)

This update also fixes the following bug :

- The snmpd service parses the /proc/diskstats file to track disk usage statistics for UCD-DISKIO-MIB::diskIOTable. On systems with a large number of block devices, /proc/diskstats may be large in size and parsing it can take a non-trivial amount of CPU time. With this update, Net-SNMP introduces a new option, 'diskio', in the /etc/snmp/snmpd.conf file, which can be used to explicitly specify devices that should be monitored. Only these whitelisted devices are then reported in UCD-DISKIO- MIB::diskIOTable, thus speeding up snmpd on systems with numerous block devices.

After installing this update, the snmpd service will be restarted automatically.

Solution

Update the affected packages.
