Multiple stack-based buffer overflows in the ICQ parsing routines of the ISS Protocol Analysis Module (PAM) component, as used in various RealSecure, Proventia, and BlackICE products, allow remote attackers to execute arbitrary code via a SRV_MULTI response containing a SRV_USER_ONLINE response packet and a SRV_META_USER response packet with long (1) nickname, (2) firstname, (3) lastname, or (4) email address fields, as exploited by the Witty worm.
Heap-based buffer overflow in the ISS Protocol Analysis Module (PAM), as used in certain versions of RealSecure Network 7.0 and Server Sensor 7.0, Proventia A, G, and M Series, RealSecure Desktop 7.0 and 3.6, RealSecure Guard 3.6, RealSecure Sentry 3.6, BlackICE PC Protection 3.6, and BlackICE Server Protection 3.6, allows remote attackers to execute arbitrary code via an SMB packet containing an authentication request with a long username.
BlackICE Defender 2.9.cap and Server Protection 3.5.cdf, when configured to automatically block attacks, allows remote attackers to block IP addresses and cause a denial of service via spoofed packets.
Unknown vulnerability in an ISAPI plugin for ISS Server Sensor 7.0 XPU 20.16, 20.18, and possibly other versions before 20.19, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code in Internet Information Server (IIS) via a certain URL through SSL.
BlackICE Agent 3.1.eal does not always reactivate after a system standby, which could allow remote attackers and local users to bypass intended firewall restrictions.
The default configuration of BlackICE Agent 3.1.eal and 3.1.ebh has a high tcp.maxconnections setting, which could allow remote attackers to cause a denial of service (memory consumption) via a large number of connections to the BlackICE system that consumes more resources than intended by the user.
Buffer overflow in the parsing mechanism for ISS Internet Scanner 6.2.1, when using the license banner HTTP check, allows remote attackers to execute arbitrary code via a long web server response.
ISS RealSecure for Nokia devices before IPSO build 6.0.2001.141d is configured to allow a user "skank" on a machine "starscream" to become a key manager when the "first time connection" feature is enabled and before any legitimate administrators have connected, which could allow remote attackers to gain access to the device during installation.
Buffer overflow in ISS BlackICE Defender 2.9 and earlier, BlackICE Agent 3.0 and 3.1, and RealSecure Server Sensor 6.0.1 and 6.5 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a flood of large ICMP ping packets.
