(Red Hat Issues Fix) Net-snmp Incomplete Parsing in snmp_pdu_parse() Lets Remote Users Crash snmpd or Execute Arbitrary Code
SecurityTracker Alert ID:  1033307
SecurityTracker URL:  http://securitytracker.com/id/1033307
CVE Reference:   CVE-2015-5621   (Links to External Site)
Date:  Aug 18 2015
Impact:   Denial of service via network, Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   A vulnerability was reported in Net-snmp. A remote user can cause the target service to crash. A remote user can execute arbitrary code on the target system.

A remote user can send specially crafted data to trigger a parsing error in snmp_pdu_parse() and cause the target snmpd process to crash or execute arbitrary code on the target system. The code will run with the privileges of the target snmp service.

Qinghao Tang of QIHU 360, China, reported this vulnerability.

Impact:   A remote user can cause the target service to crash.

A remote user can execute arbitrary code on the target system.

Solution:   Red Hat has issued a fix.

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.

It was discovered that the snmp_pdu_parse() function could leave
incompletely parsed varBind variables in the list of variables. A remote,
unauthenticated attacker could use this flaw to crash snmpd or,
potentially, execute arbitrary code on the system with the privileges of
the user running snmpd. (CVE-2015-5621)

Red Hat would like to thank Qinghao Tang of QIHU 360 company, China for
reporting this issue.

All net-snmp users are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue.
