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_InternAtom, Tk_GetAtomName - manage cache of X atoms

SYNOPSIS

#include <tk.h>

Atom Tk_InternAtom(tkwin, name)

char * Tk_GetAtomName(tkwin, atom)

ARGUMENTS

Tk_Window tkwin (in)

Token for window. Used to map atom or name relative to a particular display.

char *name (in)

String name for which atom is desired.

Atom atom (in)

Atom for which corresponding string name is desired.

DESCRIPTION

These procedures are similar to the Xlib procedures XInternAtom and XGetAtomName. Tk_InternAtom returns the atom identifier associated with string given by name; the atom identifier is only valid for the display associated with tkwin. Tk_GetAtomName returns the string associated with atom on tkwin's display. The string returned by Tk_GetAtomName is in Tk's storage: the caller need not free this space when finished with the string, and the caller should not modify the contents of the returned string. If there is no atom atom on tkwin's display, then Tk_GetAtomName returns the string ``?bad atom?''.

Tk caches the information returned by Tk_InternAtom and Tk_GetAtomName so that future calls for the same information can be serviced from the cache without contacting the server. Thus Tk_InternAtom and Tk_GetAtomName are generally much faster than their Xlib counterparts, and they should be used in place of the Xlib procedures.
