A quick overview might help in prioritizing your actions.

Advisory	CVEs	Cisco's CVSS 2.0 base score	Impact

PPTP	CVE-2008-1151 CVE-2008-1150	7.1 4.3	DoS
DLSw	Multiple vulnerabilities in the Data-link Switching (DLSw) feature when processing UDP or IP protocol 91 packets lead to Denial of Service. DLSw is used to carry SNA and NetBIOS over IP.
DLSw	CVE-2008-1152	7.8	DoS
IPv4IPv6	Dual stack (IPv4 and IPv6) routers have a vulnerability when targeted with crafted IPv6 UDP packets in certain conditions

queue	CVE-2008-0537	7.8	DoS
mvpn	Cisco's implementation of Multicast Virtual Private Network (MVPN) is vulnerable to extra multicast state creation. [MVPN is to support multicast traffic in a MPLS VPN]
mvpn	CVE-2008-1156	7.5	Extra multicast states can be created resulting a.o. in a potential for leaking multicast traffic from one MPLS VPN to another. Note: MPLS VPNs do not use encryption, they only separate the data.
