Scientific Linux Security Update : net-snmp on SL6.x i386/x86_64 (20120620)

low Nessus Plugin ID 61342

Synopsis

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

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 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)

These updated net-snmp packages also include numerous bug fixes.

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.

Solution

Update the affected packages.
