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-2003-0107 (2003-03-07)

Buffer overflow in the gzprintf function in zlib 1.1.4, when zlib is compiled without vsnprintf or when long inputs are truncated using vsnprintf, allows attackers to cause a denial of service or possibly execute arbitrary code.

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 -.
