ISS RealSecure 3.2.1 and 3.2.2 allows remote attackers to cause a denial of service via a flood of fragmented packets with the SYN flag set.

Various Intrusion Detection Systems (IDS) including (1) Cisco Secure Intrusion Detection System, (2) Cisco Catalyst 6000 Intrusion Detection System Module, (3) Dragon Sensor 4.x, (4) Snort before 1.8.1, (5) ISS RealSecure Network Sensor 5.x and 6.x before XPU 3.2, and (6) ISS RealSecure Server Sensor 5.5 and 6.0 for Windows, allow remote attackers to evade detection of HTTP attacks via non-standard "%u" Unicode encoding of ASCII characters in the requested URL.

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.

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.

Memory leak in RealSecure Event Collector 6.5 allows attackers to cause a denial of service (memory consumption and crash).

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.

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.

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.

Buffer overflow in blackd.exe for BlackICE PC Protection 3.6 and other versions before 3.6.ccb, with application protection off, allows local users to gain system privileges by modifying the .INI file to contain a long packetLog.fileprefix value.

ISS BlackIce 3.6, as used in multiple products including BlackICE PC Protection, Server Protection, Agent for Server, and RealSecure Desktop 3.6 and 7.0, does not drop privileges before launching help from the "More Info" button in the "Application Protection" dialog, which allows local users to execute arbitrary programs as SYSTEM.

The SMB Mailslot parsing functionality in PAM in multiple ISS products with XPU (24.39/1.78/epj/x.x.x.1780), including Proventia A, G, M, Server, and Desktop, BlackICE PC and Server Protection 3.6, and RealSecure 7.0, allows remote attackers to cause a denial of service (infinite loop) via a crafted SMB packet that is not properly handled by the SMB_Mailslot_Heap_Overflow decode.
