https://notcve.org/view.php?id=CVE-2011-2501
The png_format_buffer function in pngerror.c in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before 1.5.4 allows remote attackers to cause a denial of service (application crash) via a crafted PNG image that triggers an out-of-bounds read during the copying of error-message data. NOTE: this vulnerability exists because of a CVE-2004-0421 regression. NOTE: this is called an off-by-one error by some sources. La función png_format_buffer en pngerror.c en libpng v1.0.x antes de v1.0.55, en v1.2.x antes de v1.2.45, en v1.4.x antes de v1.4.8, y en v1.5.x antesde v1.5.4, permite a atacantes remotos causar una denegación de servicio (caída de aplicación) a través de una imagen PNG creada que desencadena una lectura out-of-bounds durante la copia de los datos del mensaje de error. NOTA: esta vulnerabilidad existe debido a una regresión CVE-2004-0421. • http://libpng.git.sourceforge.net/git/gitweb.cgi?p=libpng/libpng%3Ba=commit%3Bh=65e6d5a34f49acdb362a0625a706c6b914e670af http://lists.fedoraproject.org/pipermail/package-announce/2011-July/062720.html http://lists.fedoraproject.org/pipermail/package-announce/2011-July/063118.html http://secunia.com/advisories/45046 http://secunia.com/advisories/45289 http://secunia.com/advisories/45405 http://secunia.com/advisories/45415 http://secunia.com/advisories/45460 http://secunia.com/advisories/45486 http://s • CWE-125: Out-of-bounds Read •

The Curl_input_negotiate function in http_negotiate.c in libcurl 7.10.6 through 7.21.6, as used in curl and other products, always performs credential delegation during GSSAPI authentication, which allows remote servers to impersonate clients via GSSAPI requests. La función Curl_input_negotiate en http_negotiate.c en libcurl v7.10.6 a v7.21.6, tal y como se utiliza en curl y otras aplicaciones, siempre lleva a cabo delegación de credenciales durante la autenticación GSSAPI, lo que permite a hacerse pasar por clientes legitimos a servidores remotos a través de peticiones GSSAPI. • http://curl.haxx.se/curl-gssapi-delegation.patch http://curl.haxx.se/docs/adv_20110623.html http://lists.apple.com/archives/security-announce/2012/Feb/msg00000.html http://lists.fedoraproject.org/pipermail/package-announce/2011-July/062287.html http://lists.fedoraproject.org/pipermail/package-announce/2011-June/061992.html http://secunia.com/advisories/45047 http://secunia.com/advisories/45067 http://secunia.com/advisories/45088 http://secunia.com/advisories/45144 http://secunia.com/ • CWE-255: Credentials Management Errors •
