Summary: Updated net-snmp packages that fix one security issue and multiple bugs are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 3. Description: 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. An array index error, leading to an out-of-bounds buffer read flaw, was found in the way the net-snmp agent looked up entries in the extension table. A remote attacker with read privileges to aManagement 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) These updated net-snmp packages also include numerous bug fixes. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.3 Technical Notes for information on the most significant of these changes. All users of net-snmp are advised to upgrade to these updated packages, which contain backported patches to resolve these issues. After installing the update, the snmpd and snmptrapd daemons will be restarted automatically. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258 5. Bugs fixed (https://bugzilla.redhat.com/): 736580 - snmpd memory leak when AgentX subagent disconnects while processing a request 748410 - hrStorageSize from HOST-RESOURCES-TYPES mib reports incorrect size for filesystems > 16TB 754275 - Cannot create new rows in snmpTargetAddrTable 757685 - net-snmp ignores reiserfs formatted partitions 786931 - sysObjectID cannot be set to an OID value with a length greater than 10. 788954 - snmpd: error finding row index in _ifXTable_container_row_restore 799291 - proxied OIDs unspecified in proxy statement in snmpd.conf 815813 - CVE-2012-2141 net-snmp: Array index error, leading to out-of heap-based buffer read (snmpd crash) 822480 - move /var/lib/net-snmp from net-snmp to net-snmp-libs 6.
