CVE-2010-1321 – krb5: null pointer dereference in GSS-API library leads to DoS (MITKRB5-SA-2010-005)
https://notcve.org/view.php?id=CVE-2010-1321
The kg_accept_krb5 function in krb5/accept_sec_context.c in the GSS-API library in MIT Kerberos 5 (aka krb5) through 1.7.1 and 1.8 before 1.8.2, as used in kadmind and other applications, does not properly check for invalid GSS-API tokens, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via an AP-REQ message in which the authenticator's checksum field is missing. Vulnerabilidad en la función "kg_accept_krb5" en "krb5/accept_sec_context.c" de la librería GSS-API en MIT Kerberos v5 (también conocido como krb5) a través de v1.7.1 y v1.8 anterior a v1.8.2, como los usados en "kadmind" y otras aplicaciones, no comprueban adecuadamente vales (tokens) GSS-API inválidos, que permiten a usuarios autenticados remotamente causar una denegación de servicio (referencia a puntero nulo y caída del demonio) a través de un mensaje AP-REQ en el cual se pierde el campo "checksum" del usuario autenticado. • http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c02257427 http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041615.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041645.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041654.html http://lists.opensuse.org/opensuse-security-announce/2010-06/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2010-08/msg00001.html http://lists.opensuse.org/opensuse-security-announce • CWE-476: NULL Pointer Dereference •
CVE-2010-1866 – PHP 5.3 - 'PHP_dechunk()' HTTP Chunked Encoding Integer Overflow
https://notcve.org/view.php?id=CVE-2010-1866
The dechunk filter in PHP 5.3 through 5.3.2, when decoding an HTTP chunked encoding stream, allows context-dependent attackers to cause a denial of service (crash) and possibly trigger memory corruption via a negative chunk size, which bypasses a signed comparison, related to an integer overflow in the chunk size decoder. El filtro dechunk en PHP 5.3 hasta v.5.3.2, cuando se decodifica un cadena HTTP fragmentada, permite a atacantes depediendo del contexto provocar una denegación de servicio (caída) y posiblemente una corrupción de memoria mediante un tamaño de fragmento negativo, lo que evita la comparación de signo, relativo a un desbordamiento de entero en el decodificados de tamaño del fragmento. • https://www.exploit-db.com/exploits/33920 http://lists.opensuse.org/opensuse-security-announce/2010-09/msg00006.html http://php-security.org/2010/05/02/mops-2010-003-php-dechunk-filter-signed-comparison-vulnerability/index.html • CWE-190: Integer Overflow or Wraparound •
CVE-2010-0050 – Apple Webkit Blink Event Dangling Pointer Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2010-0050
Use-after-free vulnerability in WebKit in Apple Safari before 4.0.5 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via an HTML document with improperly nested tags. Vulnerabilidad uso después de la liberación (use-after-free) en Apple Safari anterior v4.0.5 permite a atacantes remotos ejecutar código de su elección o causar una denegación de servicio (caída de aplicación) a través de un documento HTML con etiquetas inadecuadamente anidadas. This vulnerability allows remote attackers to execute arbitrary code on vulnerable software utilizing Apple's WebKit library. User interaction is required to exploit this vulnerability in that the target must visit a malicious page. The specific flaw exists due to a failure to unregister a callback pointer during the destruction of a particular type of element when embedded inside a 'blink' container. The application dereferences the original resource which can can be leveraged by an attacker to execute arbitrary code under the context of the current user. • https://www.exploit-db.com/exploits/12425 http://lists.apple.com/archives/security-announce/2010/Jun/msg00003.html http://lists.apple.com/archives/security-announce/2010/Mar/msg00000.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041383.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041432.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041436.html http://lists.opensuse.org/opensuse-security-announce/2011-01/msg00006.html http: • CWE-416: Use After Free •
CVE-2009-2816
https://notcve.org/view.php?id=CVE-2009-2816
The implementation of Cross-Origin Resource Sharing (CORS) in WebKit, as used in Apple Safari before 4.0.4 and Google Chrome before 3.0.195.33, includes certain custom HTTP headers in the OPTIONS request during cross-origin operations with preflight, which makes it easier for remote attackers to conduct cross-site request forgery (CSRF) attacks via a crafted web page. La implementación de Cross-Origin Resource Sharing (CORS) en WebKit, tal como es usado en Safari de Apple anterior a versión 4.0.4 y Chrome de Google anterior a versión 3.0.195.33, incluye ciertos encabezados HTTP personalizados en la petición OPTIONS durante operaciones entre orígenes con comprobación previa, lo que facilita a los atacantes remotos conducir ataques de tipo cross-site request forgery (CSRF) por medio de una página web especialmente diseñada. • http://lists.apple.com/archives/security-announce/2009/Nov/msg00001.html http://lists.apple.com/archives/security-announce/2010/Jun/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2011-01/msg00006.html http://osvdb.org/59940 http://osvdb.org/59967 http://secunia.com/advisories/37346 http://secunia.com/advisories/37358 http://secunia.com/advisories/37393 http://secunia.com/advisories/37397 http://secunia.com/advisories/43068 http://support.apple.com/kb/HT39 • CWE-352: Cross-Site Request Forgery (CSRF) •
CVE-2009-1699 – WebKit - XML External Entity Information Disclosure
https://notcve.org/view.php?id=CVE-2009-1699
The XSL stylesheet implementation in WebKit in Apple Safari before 4.0, iPhone OS 1.0 through 2.2.1, and iPhone OS for iPod touch 1.1 through 2.2.1 does not properly handle XML external entities, which allows remote attackers to read arbitrary files via a crafted DTD, as demonstrated by a file:///etc/passwd URL in an entity declaration, related to an "XXE attack." La implementación de la hoja de estilo XSL en WebKit en Apple Safari anterior a v4.0 no maneja adecuadamente las entidades externas XML, lo cual permite a atacantes remotos leer ficheros arbitrarios a través de un DTD elaborado, como lo demuestra un fichero: ///etc/passwd URL en una declaración de entidad, relacionado con un "ataque XXE". • https://www.exploit-db.com/exploits/33034 http://lists.apple.com/archives/security-announce/2009/Jun/msg00005.html http://lists.apple.com/archives/security-announce/2009/jun/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2011-01/msg00006.html http://osvdb.org/54972 http://scary.beasts.org/security/CESA-2009-006.html http://scarybeastsecurity.blogspot.com/2009/06/apples-safari-4-fixes-local-file-theft.html http://secunia.com/advisories/35379 http://secunia.com/ad • CWE-611: Improper Restriction of XML External Entity Reference •
