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.

NAME

Tk_OwnSelection - make a window the owner of the primary selection

SYNOPSIS

#include <tk.h>

Tk_OwnSelection(tkwin, selection, proc, clientData)

ARGUMENTS

Tk_Window tkwin (in)

Window that is to become new selection owner.

Atom selection (in)

The name of the selection to be owned, such as XA_PRIMARY.

Tk_LostSelProc *proc (in)

Procedure to invoke when tkwin loses selection ownership later.

ClientData clientData (in)

Arbitrary one-word value to pass to proc.

DESCRIPTION

Tk_OwnSelection arranges for tkwin to become the new owner of the selection specified by the atom selection. After this call completes, future requests for the selection will be directed to handlers created for tkwin using Tk_CreateSelHandler. When tkwin eventually loses the selection ownership, proc will be invoked so that the window can clean itself up (e.g. by unhighlighting the selection). Proc should have arguments and result that match the type Tk_LostSelProc:

typedef void Tk_LostSelProc(ClientData clientData);

The clientData parameter to proc is a copy of the clientData argument given to Tk_OwnSelection, and is usually a pointer to a data structure containing application-specific information about tkwin.

KEYWORDS
