The Symantec NAVOPTS.DLL ActiveX control (aka Symantec.Norton.AntiVirus.NAVOptions) 126.96.36.199, as used in Norton AntiVirus, Internet Security, and System Works 2005 and 2006, is designed for use only in application-embedded web browsers, which allows remote attackers to crash the control via unspecified vectors related to content on a web site, and place Internet Explorer into a defunct state in which remote attackers can execute arbitrary code in addition to other Symantec ActiveX controls, regardless of whether they are marked safe for scripting. NOTE: this CVE was inadvertently used for an E-mail Auto-Protect issue, but that issue has been assigned CVE-2007-3771.
The software constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.

When software allows a user’s input to contain code syntax, it might be possible for an attacker to craft the code in such a way that it will alter the intended control flow of the software. Such an alteration could lead to arbitrary code execution. Injection problems encompass a wide variety of issues – all mitigated in very different ways. For this reason, the most effective way to discuss these weaknesses is to note the distinct features which classify them as injection weaknesses. The most important issue to note is that all injection problems share one thing in common – i.e., they allow for the injection of control plane data into the user-controlled data plane. This means that the execution of the process may be altered by sending code in through legitimate data channels, using no other mechanism. While buffer overflows, and many other flaws, involve the use of some further issue to gain execution, injection problems need only for the data to be parsed. The most classic instantiations of this category of weakness are SQL injection and format string vulnerabilities.
