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_QueueWindowEvent - Add a window event to the Tcl event queue

SYNOPSIS

#include <tk.h>

Tk_QueueWindowEvent(eventPtr, position)

ARGUMENTS

XEvent *eventPtr (in)

An event to add to the event queue.

Tcl_QueuePosition position (in)

Where to add the new event in the queue: TCL_QUEUE_TAIL, TCL_QUEUE_HEAD, or TCL_QUEUE_MARK.

DESCRIPTION

This procedure places a window event on Tcl's internal event queue for eventual servicing. It creates a Tcl_Event structure, copies the event into that structure, and calls Tcl_QueueEvent to add the event to the queue. When the event is eventually removed from the queue it is processed just like all window events.

The position argument to Tk_QueueWindowEvent has the same significance as for Tcl_QueueEvent; see the documentation for Tcl_QueueEvent for details.
