DESCRIPTION:
Multiple vulnerabilities have been reported in Cisco ASA 5500 Series
Adaptive Security Appliances and Cisco Catalyst 6500 Series ASA
Services Module (ASASM), which can be exploited by malicious people
to cause a DoS (Denial of Service) or compromise a vulnerable
system.
1) An error during memory allocation for an internal DHCP data
structure when processing DHCP requests can be exploited to cause a
device reload via a specially crafted transit or direct DHCP
request.
Successful exploitation requires the DHCP relay or DHCP server
feature to be enabled.
2) An error in the AAA (Authentication, Authorization, and
Accounting) code when handling SSL VPN authentication can be
exploited to cause a device reload via a specially crafted
authentication challenge-response.
Successful exploitation requires Cisco ASA software configured for
Clientless or AnyConnect SSL VPN.
3) An error within the SIP (Session Initiation Protocol) inspection
engine can be exploited to cause a device reload via a specially
crafted SIP media update packet.
Successful exploitation requires that SIP inspection is enabled.
4) Some vulnerabilities exist in the DCERPC inspection engine.
