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-2007-4772 (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-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.

NAME

Tk::Widget - Base class of all widgets

SYNOPSIS

package Tk::Whatever;
require Tk::Widget;
@ISA = qw(Tk::Widget);   
Construct Tk::Widget 'Whatever';

sub Tk_cmd { \&Tk::whatever }

DESCRIPTION

The Tk::Widget is an abstract base class for all Tk widgets.

Generic methods available to all widgets include:

Getimage( name )

Given name, look for an image file with that base name and return a Tk::Image. File extensions are tried in this order: xpm, gif, ppm, xbm until a valid iamge is found. If no image is found, try a builtin image with that name.

EventType( ?value? )

Return or set the tixEvent variable option. Currently, the only option used is "type".

CAVEATS

The above documentaion on generic methods is catastrophically incomplete.
