CVE-2011-2692 – libpng: Invalid read when handling empty sCAL chunks
https://notcve.org/view.php?id=CVE-2011-2692
The png_handle_sCAL function in pngrutil.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 does not properly handle invalid sCAL chunks, which allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via a crafted PNG image that triggers the reading of uninitialized memory. La función png_handle_sCAL de pngrutil.c en libpng v1.0.x antes de la v1.0.55, en v1.2.x antes de la v1.2.45, en v1.4.x antes de la v1.4.8, y en v1.5.x antes de la v1.5.4, no controla correctamente fragmentos inválidos SCAL, que permiten a atacantes remotos causar una denegación de servicio (corrupción de memoria y caída de aplicación) o posiblemente tener un impacto no especificado a través de una imagen PNG creada que provoca la lectura de la memoria sin inicializar. • http://libpng.git.sourceforge.net/git/gitweb.cgi?p=libpng/libpng%3Ba=commit%3Bh=61a2d8a2a7b03023e63eae9a3e64607aaaa6d339 http://lists.apple.com/archives/Security-announce/2011//Oct/msg00003.html http://lists.apple.com/archives/security-announce/2012/May/msg00001.html http://lists.fedoraproject.org/pipermail/package-announce/2011-July/063118.html http://secunia.com/advisories/45046 http://secunia.com/advisories/45405 http://secunia.com/advisories/45415 http://secunia.com/advisories/45445 http://secun • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

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.

CVE-2011-2192 – curl: Improper delegation of client credentials during GSS negotiation
https://notcve.org/view.php?id=CVE-2011-2192
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 •
