CentOS Update for net-snmp CESA-2013:0124 centos5

Published: 2013-01-21 04:09:45
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:M/Au:S/C:N/I:N/A:P

Summary:
The remote host is missing an update for the 'net-snmp' Linux Distribution Package(s) announced via the referenced advisory.

Affected Versions:
net-snmp on CentOS 5

Recommendations:
Please install the updated Linux Distribution Packages.

Technical Details:
These Linux Distribution Packages provide various libraries and tools for the Simple Network Management Protocol (SNMP). An out-of-bounds buffer read flaw was found in the net-snmp agent. A remote attacker with read privileges to a Management Information Base (MIB) subtree handled by the 'extend' directive (in '/etc/snmp/snmpd.conf') could use this flaw to crash snmpd via a crafted SNMP GET request. (CVE-2012-2141) Bug fixes: * Devices that used certain file systems were not reported in the 'HOST-RESOURCES-MIB::hrStorageTable' table. As a result, the snmpd daemon did not recognize devices using tmpfs, ReiserFS, and Oracle Cluster File System (OCFS2) file systems. This update recognizes these devices and reports them in the 'HOST-RESOURCES-MIB::hrStorageTable' table. (BZ#754652, BZ#755958, BZ#822061) * The snmptrapd (8) man page did not correctly describe how to load multiple configuration files using the '-c' option. This update describes correctly that multiple configuration files must be separated by a comma. (BZ#760001) * Integers truncated from 64 to 32-bit were not correctly evaluated. As a consequence, the snmpd daemon could enter an endless loop when encoding the truncated integers to network format. This update modifies the underlying code so that snmpd correctly checks truncated 64-bit integers. Now, snmpd avoids an endless loop. (BZ#783892) * snmpd did not correctly check for interrupted system calls when enumerating existing IPv6 network prefixes during startup. As a consequence, snmpd could prematurely exit when receiving a signal during this enumeration. This update checks the network prefix enumeration code for interrupted system calls. Now, snmpd no longer terminates when a signal is received. (BZ#799699) * snmpd used the wrong length of COUNTER64 values in the AgentX protocol. As a consequence, snmpd could not decode two consecutive COUNTER64 values in one AgentX packet. This update uses the correct COUNTER64 size and can process two or mode COUNTER64 values in AgentX communication. (BZ#803585) * snmpd ignored the '-e' parameter of the 'trapsess' option in the snmpd configuration file. As a result, outgoing traps were incorrectly sent with the default EngineID of snmpd when configuring 'trapsess' with an explicit EngineID. This update modifies the underlying code to send outgoing traps using the EngineID as specified in the 'trapsess -e' parameter in the configuration file. (BZ#805689) * snmpd did not cor ...

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
