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

Tk::Scrolled - Create a widget with attached scrollbar(s)

SYNOPSIS

    $whatever = $parent->Scrolled('Whatever',
				-scrollbars = 'nw',
				... widget options of Whatever here...
				);

DESCRIPTION

To stop a flood of ScrlWhatever Perl/Tk introcuded the special constructor Scrolled. Scrolled creates a widget of the given Class 'Whatever' with attached scrollbar(s).

OPTIONS

-scrollbars

Expects as argument the position where the scrollbars should be created. 'w', 'e' or 'n', 's' or a combination of them. If the one or both positions are prefixed with 'o' the scrollbar will only show up if there is a 'real' need to scroll.

all other option

All options beside <-scrollbars> are passed to the 'Whatever' widget constructor.

BUGS

If a widget does not support -{x,y}scrollcommand options, Scrolled does not complain if the specified widget class does not support them. E.g.,

$parent->Scrolled('Button', ...)

One does not get an error message or warning when one tries to configure scrollbars after the widget construction:

$ascrolled->scrollbars('e')
$ascrolled->configure(-scrollbars => 'e');
