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::Pixmap - Create color images from XPM files.

SYNOPSIS

$widget->Pixmap?(name?,options?)?

DESCRIPTION

XPM is a popular X Window image file format for storing color icons. The Pixmap image type can be used to create color images using XPM files.

Pixmaps support the following options:

-data => string

Specifies the contents of the source pixmap as a string. The string must adhere to the XPM file format (e.g., as generated by the pixmap(1) program). If both the -data and -file options are specified, the -data option takes precedence. Please note that the XPM file parsing code in the xpm library is somewhat fragile. The first line of the string must be "/* XPM */" or otherwise a segmatation fault will be caused.

-file => name

name gives the name of a file whose contents define the source pixmap. The file must adhere to the XPM file format (e.g., as generated by the pixmap(1) program).

IMAGE METHODS

When a pixmap image is created, Tk also creates a new object. This object supports the configure and cget methods described in Tk::options which can be used to enquire and modify the options described above.
