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::After - support class for Tk::Widget::after

SYNOPSIS

$id = $widget->after(time,callback);
$id = $widget->afterIdle(callback);
$widget->afterCancel($id);

$id = $widget->repeat(period,callback);

Internally this class is used to implement above.

$id = Tk::After->new($widget,$time,'method',callback);
$id->cancel;

DESCRIPTION

This class is a wrapper used by Tk::Widget::after to auto-cancel after calls when a widget is destroyed.

callback is a normal perl/Tk callback. Method is either 'once' or 'repeat'

This is first attempt at the code and interface is likely to change. So for the time being at least use $widget->after(...) interface.
