Oracle Solaris Third-Party Patch Update : quagga (multiple_denial_of_service_vulnerabilities4)

Description

The remote Solaris system is missing necessary patches to address security updates : - bgpd in Quagga before 0.99.9 allows explicitly configured BGP peers to cause a denial of service (crash) via a malformed (1) OPEN message or (2) a COMMUNITY attribute, which triggers a NULL pointer dereference. NOTE: vector 2 only exists when debugging is enabled. (CVE-2007-4826) - The BGP daemon (bgpd) in Quagga 0.99.11 and earlier allows remote attackers to cause a denial of service (crash) via an AS path containing ASN elements whose string representation is longer than expected, which triggers an assert error. (CVE-2009-1572) - The extended-community parser in bgpd in Quagga before 0.99.18 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a malformed Extended Communities attribute. (CVE-2010-1674) - bgpd in Quagga before 0.99.18 allows remote attackers to cause a denial of service (session reset) via a malformed AS_PATHLIMIT path attribute. (CVE-2010-1675) - Stack-based buffer overflow in the bgp_route_refresh_receive function in bgp_packet.c in bgpd in Quagga before 0.99.17 allows remote authenticated users to cause a denial of service (daemon crash) or possibly execute arbitrary code via a malformed Outbound Route Filtering (ORF) record in a BGP ROUTE-REFRESH (RR) message. (CVE-2010-2948) - bgpd in Quagga before 0.99.17 does not properly parse AS paths, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an unknown AS type in an AS path attribute in a BGP UPDATE message. (CVE-2010-2949) - The OSPFv3 implementation in ospf6d in Quagga before 0.99.19 allows remote attackers to cause a denial of service (out-of-bounds memory access and daemon crash) via a Link State Update message with an invalid IPv6 prefix length. (CVE-2011-3323) - The ospf6_lsa_is_changed function in ospf6_lsa.c in the OSPFv3 implementation in ospf6d in Quagga before 0.99.19 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via trailing zero values in the Link State Advertisement (LSA) header list of an IPv6 Database Description message. (CVE-2011-3324) - ospf_packet.c in ospfd in Quagga before 0.99.19 allows remote attackers to cause a denial of service (daemon crash) via (1) a 0x0a type field in an IPv4 packet header or (2) a truncated IPv4 Hello packet. (CVE-2011-3325) - The ospf_flood function in ospf_flood.c in ospfd in Quagga before 0.99.19 allows remote attackers to cause a denial of service (daemon crash) via an invalid Link State Advertisement (LSA) type in an IPv4 Link State Update message. (CVE-2011-3326)
