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::BrowseEntry - entry widget with popup choices.

SYNOPSIS

use Tk::BrowseEntry;

$b = $frame->BrowseEntry(-label => "Label", -variable => \$var);
$b->insert("end", "opt1");
$b->insert("end", "opt2");
$b->insert("end", "opt3");
...
$b->pack;

DESCRIPTION

BrowseEntry is a poor man's ComboBox. It may be considered an enhanced version of LabEntry which provides a button to popup the choices of the possible values that the Entry may take. BrowseEntry supports all the options LabEntry supports except -textvariable. This is replaced by -variable. Other options that BrowseEntry supports.

-listwidth

Specifies the width of the popup listbox.

-variable

Specifies the variable in which the entered value is to be stored.

-browsecmd

Specifies a function to call when a selection is made in the popped up listbox. It is passed the widget and the text of the entry selected. This function is called after the entry variable has been assigned the value.

-listcmd

Specifies the function to call when the button next to the entry is pressed to popup the choices in the listbox. This is called before popping up the listbox, so can be used to populate the entries in the listbox.

METHODS

insert(index, string)

Inserts the text of string at the specified index. This string then becomes available as one of the choices.

delete(index1, index2)

Deletes items from index1 to index2.

BUGS

BrowseEntry should really provide more of the ComboBox options.
