The png_check_keyword function in pngwutil.c in libpng before 1.0.42, and 1.2.x before 1.2.34, might allow context-dependent attackers to set the value of an arbitrary memory location to zero via vectors involving creation of crafted PNG files with keywords, related to an implicit cast of the '\0' character constant to a NULL pointer. NOTE: some sources incorrectly report this as a double free vulnerability. La funcion png_check_keyword en pngwutil.c en libpng anteriores a v1.0.42, v1.2.x anterior a v1.2.34, permitiría atacantes dependientes de contexto poner a cero el valor de una localización de memoria de su elección a través de vectores relacionados con la creación de ficheros PNG con palabras clave, relacionado con la asignación del valor '\0' a un puntero NULL. NOTA: Algunas fuentes informan incorrectamente que se trata de una vulnerabilidad de doble liberación. • http://libpng.sourceforge.net/index.html http://lists.opensuse.org/opensuse-security-announce/2009-02/msg00000.html http://openwall.com/lists/oss-security/2009/01/09/1 http://secunia.com/advisories/34320 http://secunia.com/advisories/34388 http://security.gentoo.org/glsa/glsa-200903-28.xml http://sourceforge.net/mailarchive/forum.php?thread_name=4B6F0239C13D0245820603C036D180BC79FBAA%40CABOTUKEXCH01.cabot.local&forum_name=png-mng-implement http://www.debian.org/security/2009/dsa-1750 http://www&# •

Multiple off-by-one errors in libpng before 1.2.32beta01, and 1.4 before 1.4.0beta34, allow context-dependent attackers to cause a denial of service (crash) or have unspecified other impact via a PNG image with crafted zTXt chunks, related to (1) the png_push_read_zTXt function in pngread.c, and possibly related to (2) pngtest.c. Múltiples desbordamientos de entero en libpng versiones anteriores a 1.2.32beta01, y 1.4 versiones anteriores a 1.4.0beta34, permiten a atacantes dependientes de contexto provocar una denegación de servicio (caída) o tener otros impactos desconocidos a través de una imagen PNG con fragmentos zTXt manipulados, relacionado con (1) la función png_push_read_zTXt en pngread.c, y posiblemente relacionado con (2) pngtest.c. • http://secunia.com/advisories/31781 http://secunia.com/advisories/33137 http://secunia.com/advisories/35302 http://secunia.com/advisories/35386 http://security.gentoo.org/glsa/glsa-200812-15.xml http://sourceforge.net/mailarchive/forum.php?thread_name=e56ccc8f0809180317u6a5306fg14683947affb3e1b%40mail.gmail.com&forum_name=png-mng-implement http://sourceforge.net/project/shownotes.php?group_id=5624&release_id=624517 http://sourceforge.net/project/shownotes.php?release_id=624518 http://sourceforge.net/tracker& • CWE-193: Off-by-one Error •

libpng 1.0.6 through 1.0.32, 1.2.0 through 1.2.26, and 1.4.0beta01 through 1.4.0beta19 allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a PNG file with zero length "unknown" chunks, which trigger an access of uninitialized memory. libpng versions de la 1.0.6 hasta la 1.0.32, 1.2.0 hasta la 1.2.26 y 1.4.0beta01 hasta la 1.4.0beta19, permiten a atacantes dependientes del contexto provocar una denegación de servicio (caída) y posiblemente ejecutar código de su elección a través de un archivo PNG con fragmentos desconocidos de longitud cero, lo que dispara un acceso de memoria no inicializada. • http://libpng.sourceforge.net/Advisory-1.2.26.txt http://lists.apple.com/archives/security-announce//2008/Sep/msg00005.html http://lists.apple.com/archives/security-announce/2009/May/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2008-04/msg00011.html http://secunia.com/advisories/29678 http://secunia.com/advisories/29792 http://secunia.com/advisories/29957 http://secunia.com/advisories/29992 http://secunia.com/advisories/30009 http://secunia.com/advisories/301 • CWE-189: Numeric Errors •
