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

Dial - an alternative to the scale widget

SYNOPSIS

 use Tk::Dial;

 $dial = $top->Dial(-margin =>  20,
		    -radius =>  48,
		    -min    =>	 0,
		    -max    => 100,
		    -value  =>   0,
		    -format => '%d');

 margin - blank space to leave around dial
 radius - radius of dial
 min, max - range of possible values
 value  - current value
 format - printf-style format for displaying format

Values shown above are defaults.

DESCRIPTION

A dial looks like a speedometer: a 3/4 circle with a needle indicating the current value. Below the graphical dial is an entry that displays the current value, and which can be used to enter a value by hand.

The needle is moved by pressing button 1 in the canvas and dragging. The needle will follow the mouse, even if the mouse leaves the canvas, which allows for high precision. Alternatively, the user can enter a value in the entry space and press Return to set the value; the needle will be set accordingly.
