Vigil@nce - Net-SNMP: denial of service via trap
March 2014 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
An attacker can dereference a NULL pointer in snmptrapd of
Net-SNMP, in order to trigger a denial of service.
Impacted products: MBS, Net-SNMP, openSUSE
Severity: 2/4
Creation date: 05/03/2014
DESCRIPTION OF THE VULNERABILITY
The Net-SNMP product provides the snmptrapd daemon to manage SNMP
TRAP messages.
The "Community String" is a string used for SNMP authentication.
However, if the Community String is empty, the
perl_trapd_handler() function does not check if a pointer is NULL,
before using it.
An attacker can therefore dereference a NULL pointer in snmptrapd
of Net-SNMP, in order to trigger a denial of service.
