CVE-2006-4484 (2008-10-01)

Buffer overflow in the LWZReadByte_ function in the GD extension in allows remote attackers to have an unknown impact via a GIF file with input_code_size greater than MAX_LWZ_BITS, which triggers an overflow when initializing the table array.

CVE-2007-4769 (2008-01-09)

The regular expression parser in TCL before 8.4.17, as used in PostgreSQL 8.2 before 8.2.6, 8.1 before 8.1.11, 8.0 before 8.0.15, and 7.4 before 7.4.19, allows remote authenticated users to cause a denial of service (backend crash) via an out-of-bounds backref number.

CVE-2003-0107 (2003-03-07)

Buffer overflow in the gzprintf function in zlib 1.1.4, when zlib is compiled without vsnprintf or when long inputs are truncated using vsnprintf, allows attackers to cause a denial of service or possibly execute arbitrary code.

CVE-2007-4772 (2008-01-09)

The regular expression parser in TCL before 8.4.17, as used in PostgreSQL 8.2 before 8.2.6, 8.1 before 8.1.11, 8.0 before 8.0.15, and 7.4 before 7.4.19, allows context-dependent attackers to cause a denial of service (infinite loop) via a crafted regular expression.

CVE-2007-6067 (2008-01-09)

Algorithmic complexity vulnerability in the regular expression parser in TCL before 8.4.17, as used in PostgreSQL 8.2 before 8.2.6, 8.1 before 8.1.11, 8.0 before 8.0.15, and 7.4 before 7.4.19, allows remote authenticated users to cause a denial of service (memory consumption) via a crafted "complex" regular expression with doubly-nested states.

CVE-2017-12652 (2019-07-10)

libpng before 1.6.32 does not properly check the length of chunks against the user limit.

NAME

Tk_GeometryRequest, Tk_SetInternalBorder - specify desired geometry or internal border for a window

SYNOPSIS

#include <tk.h>

Tk_GeometryRequest(tkwin, reqWidth, reqHeight)

Tk_SetInternalBorder(tkwin, width)

ARGUMENTS

Tk_Window tkwin (in)

Window for which geometry is being requested.

int reqWidth (in)

Desired width for tkwin, in pixel units.

int reqHeight (in)

Desired height for tkwin, in pixel units.

int width (in)

Space to leave for internal border for tkwin, in pixel units.

DESCRIPTION

Tk_GeometryRequest is called by widget code to indicate its preference for the dimensions of a particular window. The arguments to Tk_GeometryRequest are made available to the geometry manager for the window, which then decides on the actual geometry for the window. Although geometry managers generally try to satisfy requests made to Tk_GeometryRequest, there is no guarantee that this will always be possible. Widget code should not assume that a geometry request will be satisfied until it receives a ConfigureNotify event indicating that the geometry change has occurred. Widget code should never call procedures like Tk_ResizeWindow directly. Instead, it should invoke Tk_GeometryRequest and leave the final geometry decisions to the geometry manager.

If tkwin is a top-level window, then the geometry information will be passed to the window manager using the standard ICCCM protocol.

Tk_SetInternalBorder is called by widget code to indicate that the widget has an internal border. This means that the widget draws a decorative border inside the window instead of using the standard X borders, which are external to the window's area. For example, internal borders are used to draw 3-D effects. Width specifies the width of the border in pixels. Geometry managers will use this information to avoid placing any children of tkwin overlapping the outermost width pixels of tkwin's area.

The information specified in calls to Tk_GeometryRequest and Tk_SetInternalBorder can be retrieved using the macros Tk_ReqWidth, Tk_ReqHeight, and Tk_InternalBorderWidth. See the Tk::WindowId documentation for details.
