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-2018-25032 (2022-03-25)

zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches.

CVE-2011-3045 (2012-03-22)

Integer signedness error in the png_inflate function in pngrutil.c in libpng before 1.4.10beta01, as used in Google Chrome before 17.0.963.83 and other products, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted PNG file, a different vulnerability than CVE-2011-3026.

CVE-2016-10087 (2017-01-30)

The png_set_text_2 function in libpng 0.71 before 1.0.67, 1.2.x before 1.2.57, 1.4.x before 1.4.20, 1.5.x before 1.5.28, and 1.6.x before 1.6.27 allows context-dependent attackers to cause a NULL pointer dereference vectors involving loading a text chunk into a png structure, removing the text, and then adding another text chunk to the structure.

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-2017-12652 (2019-07-10)

libpng before 1.6.32 does not properly check the length of chunks against the user limit.

NAME

Tk::clipboard - Manipulate Tk clipboard

SYNOPSIS

$widget->clipboardOption?(args)?

DESCRIPTION

This command provides an interface to the Tk clipboard, which stores data for later retrieval using the selection mechanism. In order to copy data into the clipboard, clipboardClear must be called, followed by a sequence of one or more calls to clipboardAppend. To ensure that the clipboard is updated atomically, all appends should be completed before returning to the event loop.

The following methods are currently supported:

$widget->clipboardClear

Claims ownership of the clipboard on $widget's display and removes any previous contents. Returns an empty string.

$widget->clipboardAppend(?-format=>format?,?-type=>type?,?--?,data)

Appends data to the clipboard on $widget's display in the form given by type with the representation given by format and claims ownership of the clipboard on $widget's display.

Type specifies the form in which the selection is to be returned (the desired ``target'' for conversion, in ICCCM terminology), and should be an atom name such as STRING or FILE_NAME; see the Inter-Client Communication Conventions Manual for complete details. Type defaults to STRING.

The format argument specifies the representation that should be used to transmit the selection to the requester (the second column of Table 2 of the ICCCM), and defaults to STRING. If format is STRING, the selection is transmitted as 8-bit ASCII characters. See the Tk::Selection documentation for explanation of what happens if format is not STRING. Note that arguments passed to clipboardAppend are concatenated before conversion, so the caller must take care to ensure appropriate spacing across string boundaries. All items appended to the clipboard with the same type must have the same format.

A -- argument may be specified to mark the end of options: the next argument will always be used as data. This feature may be convenient if, for example, data starts with a -.

$widget->clipboardGet( ?-type? );

Retrieve data from the clipboard on widget's display. -type specifies the form in which the data is to be returned and should be an atom name such as STRING or FILE_NAME. Type defaults to STRING. This command is equivalent to SelectionGet( -selection => 'CLIPBOARD' ).
