Problem: Multiple vulnerabilities in Net-SNMP have been resolved in the Juniper Networks Steel-Belted Radius (SBR) Carrier AAA (Authentication, Authorization, and Accounting) server. These issues affect Juniper Networks SBR Carrier versions prior to 8.4.1R19. Juniper SIRT is not aware of any malicious exploitation of these vulnerabilities. These issues were discovered during an external security research. Net-SNMP in SBR Carrier has been upgraded to Net-SNMP 5.8 which resolved the following vulnerabilities in Net-SNMP: CVE CVSS Summary 7.8 (AV:N The SNMP agent (snmp_agent.c) in net-snmp before 5.4.1 CVE-2007-5846 /AC:L/ allows remote attackers to cause a denial of service Au:N/C:N/ (CPU and memory consumption) via a GETBULK request with I:N/A:C) a large max-repeaters value. Integer overflow in the netsnmp_create_subtree_cache 5.0 (AV:N function in agent/snmp_agent.c in net-snmp 5.4 before /AC:L/ 5.4.2.1, 5.3 before 5.3.2.3, and 5.2 before 5.2.5.1 CVE-2008-4309 Au:N/C:N/ allows remote attackers to cause a denial of service I:N/A:P) (crash) via a crafted SNMP GETBULK request, which triggers a heap-based buffer overflow, related to the number of responses or repeats. The netsnmp_udp_fmtaddr function (snmplib/ 5.0 (AV:N snmpUDPDomain.c) in net-snmp 5.0.9 through 5.4.2.1, /AC:L/ when using TCP wrappers for client authorization, does CVE-2008-6123 Au:N/C:P/ not properly parse hosts.allow rules, which allows I:N/A:N) remote attackers to bypass intended access restrictions and execute SNMP queries, related to "source/ destination IP address confusion." 5.0 (AV:N The AgentX subagent in Net-SNMP before 5.4.4 allows /AC:L/ remote attackers to cause a denial of service (hang) by CVE-2014-2310 Au:N/C:N/ sending a multi-object request with an Object ID (OID) I:N/A:P) containing more subids than previous requests, a different vulnerability than CVE-2012-6151. snmplib/mib.c in net-snmp 5.7.0 and earlier, when the 5.0 (AV:N -OQ option is used, allows remote attackers to cause a CVE-2014-3565 /AC:L/ denial of service (snmptrapd crash) via a crafted SNMP Au:N/C:N/ trap message, which triggers a conversion to the I:N/A:P) variable type designated in the MIB file, as demonstrated by a NULL type in an ifMtu trap message. The snmp_pdu_parse function in snmp_api.c in net-snmp 7.5 (AV:N 5.7.2 and earlier does not remove the varBind variable CVE-2015-5621 /AC:L/ in a netsnmp_variable_list item when parsing of the Au:N/C:P/ SNMP PDU fails, which allows remote attackers to cause I:P/A:P) a denial of service (crash) and possibly execute arbitrary code via a crafted packet. Solution: The following software releases have been updated to resolve these specific issues: SBR Carrier 8.4.1R19, 8.5.0R1, and all subsequent releases. These issues are being tracked as 1386896 . Workaround: There are no viable workarounds for these issues. Implementation: Software release Service Packages are available at http://support.juniper.net from the "Download Software" links.
