T-016: iseemedia / Roxio / MGI Software LPViewer ActiveX Vulnerabilities
The iseemedia LPViewer ActiveX control contains multiple stack buffer overflows, which can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system. The risk is MEDIUM. By cinvincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), an attacker may be able to execute arbitrary code with the privileges of the user. The attacker could also cause Internet Explorer (or the program using the WebBrowser control) to crash.

NAME

       Tcl_SetRecursionLimit - set maximum allowable nesting depth in interpreter

SYNOPSIS

       #include <tcl.h>

       int
       Tcl_SetRecursionLimit(interp, depth)

ARGUMENTS

       Tcl_Interp *interp (in)		Interpreter whose recursion limit is to be set.  Must be greater than zero.

       int depth (in)			New limit for nested calls to Tcl_Eval for interp.
_________________________________________________________________

DESCRIPTION

       At  any	given  time  Tcl  enforces a limit on the number of recursive calls that may be active for Tcl_Eval and related procedures such as
       Tcl_GlobalEval.	Any call to Tcl_Eval that exceeds this depth is aborted with an error.	By default the recursion limit is 1000.

       Tcl_SetRecursionLimit may be used to change the maximum allowable nesting depth for an interpreter.  The depth  argument  specifies  a  new
       limit  for  interp,  and Tcl_SetRecursionLimit returns the old limit.  To read out the old limit without modifying it, invoke Tcl_SetRecur-
       sionLimit with depth equal to 0.

       The Tcl_SetRecursionLimit only sets the size of the Tcl call stack:  it cannot by itself prevent stack overflows on the C stack being  used
       by  the	application.  If your machine has a limit on the size of the C stack, you may get stack overflows before reaching the limit set by
       Tcl_SetRecursionLimit.  If this happens, see if there is a mechanism in your system for increasing the maximum size of the C stack.
