Mandriva Linux Security Advisory : net-snmp (MDVSA-2009:056)
Medium Nessus Plugin ID 36601
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionA vulnerability has been identified and corrected in net-snmp :
The netsnmp_udp_fmtaddr function (snmplib/snmpUDPDomain.c) in net-snmp 5.0.9 through 5.4.2, when using TCP wrappers for client authorization, does not properly parse hosts.allow rules, which allows remote attackers to bypass intended access restrictions and execute SNMP queries, related to source/destination IP address confusion.
The updated packages have been patched to prevent this.
SolutionUpdate the affected packages.
