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-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.

NAME

messageBox - pop up a message window and wait for user response.

SYNOPSIS

$response = $widget->messageBox(-option => value, ... );

DESCRIPTION

This method uses Tk::Dialog to quickly create several common dialog boxes. A dialog widget consists of a message, an icon and a set of buttons (see the -type option). After the message window is popped up, messageBox waits for the user to select one of the buttons and return the button text. NOTE: unlike Tk::Dialog which creates its widget once and can be used many times, the messageBox window is created every time it's used.

The following option/value pairs are supported:

-default

The case-sensitive symbolic name of the default button for this message window ('OK', 'Cancel' and so on). See -type for a list of the symbolic names. If the message box has just one button it will automatically be made the default, otherwise if this option is not specified, there won't be any default button.

-icon

Specifies an icon to display. Any of the builtin Tk bitmaps can specified.

-message

Specifies the message to display.

-title

Specifies a string to display as the title.

-type

Specifies a predefined set of buttons to be displayed. The following values are possible: 'AbortRetryIgnore', 'OK', 'OKCancel', 'RetryCancel', 'YesNo' or 'YesNoCancel'.

EXAMPLE

$repsonse = $mw->messageBox(-icon => 'questhead', -message => 'Hello World!', -title => 'My title', -type => 'AbortRetryIgnore', -default => 'Retry');
