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_GetVRootGeometry - Get location and size of virtual root for window

SYNOPSIS

#include <tk.h>

Tk_GetVRootGeometry(tkwin, xPtr, yPtr, widthPtr, heightPtr)

ARGUMENTS

Tk_Window tkwin (in)

Token for window whose virtual root is to be queried.

int xPtr (out)

Points to word in which to store x-offset of virtual root.

int yPtr (out)

Points to word in which to store y-offset of virtual root.

"int" widthPtr (out)

Points to word in which to store width of virtual root.

"int" heightPtr (out)

Points to word in which to store height of virtual root.

DESCRIPTION

TkGetVRootGeometry returns geometry information about the virtual root window associated with tkwin. The ``associated'' virtual root is the one in which tkwin's nearest top-level ancestor (or tkwin itself if it is a top-level window) has been reparented by the window manager. This window is identified by a __SWM_ROOT or __WM_ROOT property placed on the top-level window by the window manager. If tkwin is not associated with a virtual root (e.g. because the window manager doesn't use virtual roots) then *xPtr and *yPtr will be set to 0 and *widthPtr and *heightPtr will be set to the dimensions of the screen containing tkwin.

KEYWORDS

geometry, height, location, virtual root, width, window manager
