Insight
These 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 ...
