CVE-2014-1765 – Microsoft Internet Explorer CAttrValue Use-After-Free Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2014-1765
Multiple use-after-free vulnerabilities in Microsoft Internet Explorer 6 through 11 allow remote attackers to execute arbitrary code via unspecified vectors, as demonstrated by Sebastian Apelt and Andreas Schmidt during a Pwn2Own competition at CanSecWest 2014. Múltiples vulnerabilidades de uso después de liberación de memoria en Microsoft Internet Explorer 6 hasta la versión 11 permiten a atacantes remotos ejecutar un código arbitrario a través de vectores no especificados, tal como fue demostrado por Sebastian Apelt y Andreas Schmidt durante una competición Pwn2Own en CanSecWest 2014. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Internet Explorer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of CAttrValue objects. An uninitialized variable in one of the functions can cause memory corruption. • http://secunia.com/advisories/59775 http://twitter.com/thezdi/statuses/444216845734666240 http://www.pwn2own.com/2014/03/pwn2own-results-thursday-day-two http://www.securitytracker.com/id/1030532 https://docs.microsoft.com/en-us/security-updates/securitybulletins/2014/ms14-037 • CWE-399: Resource Management Errors •
CVE-2014-1776 – Microsoft Internet Explorer Memory Corruption Vulnerability
https://notcve.org/view.php?id=CVE-2014-1776
Use-after-free vulnerability in Microsoft Internet Explorer 6 through 11 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via vectors related to the CMarkup::IsConnectedToPrimaryMarkup function, as exploited in the wild in April 2014. NOTE: this issue originally emphasized VGX.DLL, but Microsoft clarified that "VGX.DLL does not contain the vulnerable code leveraged in this exploit. Disabling VGX.DLL is an exploit-specific workaround that provides an immediate, effective workaround to help block known attacks." Vulnerabilidad de uso después de liberación de memoria en Microsoft Internet Explorer 6 hasta la versión 11 permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (corrupción de memoria) a través de vectores relacionados con la función CMarkup::IsConnectedToPrimaryMarkup, tal como fue explotado activamente en abril de 2014. NOTA: este problema se enfatizó originalmente en VGX.DLL, pero Microsoft aclaró que "VGX.DLL no contiene el código vulnerable aprovechado en esta explotación. • http://blogs.technet.com/b/srd/archive/2014/04/30/protection-strategies-for-the-security-advisory-2963983-ie-0day.aspx http://secunia.com/advisories/57908 http://securitytracker.com/id?1030154 http://www.fireeye.com/blog/uncategorized/2014/04/new-zero-day-exploit-targeting-internet-explorer-versions-9-through-11-identified-in-targeted-attacks.html http://www.kb.cert.org/vuls/id/222929 http://www.osvdb.org/106311 http://www.securityfocus.com/bid/67075 http://www.signalsec.com/cve-20 • CWE-416: Use After Free •
CVE-2014-1764 – Microsoft Internet Explorer Protected Mode Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2014-1764
Microsoft Internet Explorer 7 through 11 allows remote attackers to execute arbitrary code and bypass a sandbox protection mechanism by leveraging "object confusion" in a broker process, as demonstrated by VUPEN during a Pwn2Own competition at CanSecWest 2014. Microsoft Internet Explorer 7 hasta la versión 11 permite a atacantes remotos ejecutar código arbitrario y eludir un mecanismo de protección sandbox aprovechando "confusión de objeto" en un proceso broker, según lo demostrado por VUPEN durante una competición Pwn2Own en CanSecWest 2014. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Internet Explorer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the processing of data shared to the broker by the sandboxed process. The issue lies in the failure to validate an object's type. • https://www.exploit-db.com/exploits/34010 http://twitter.com/thezdi/statuses/443855973673754624 http://www.pwn2own.com/2014/03/pwn2own-results-for-wednesday-day-one http://www.securityfocus.com/archive/1/532798/100/0/threaded http://www.securityfocus.com/bid/67295 http://www.securitytracker.com/id/1030370 https://docs.microsoft.com/en-us/security-updates/securitybulletins/2014/ms14-035 • CWE-264: Permissions, Privileges, and Access Controls •
CVE-2014-1762 – (Pwn2Own\Pwn4Fun) Microsoft Internet Explorer localhost Protected Mode Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2014-1762
Unspecified vulnerability in Microsoft Internet Explorer 6 through 11 allows remote attackers to execute arbitrary code with medium-integrity privileges and bypass a sandbox protection mechanism via unknown vectors, as demonstrated by ZDI during a Pwn4Fun competition at CanSecWest 2014. Vulnerabilidad no especificada en Microsoft Internet Explorer 6 hasta la versión 11 permite a atacantes remotos ejecutar código arbitario con privilegios de integridad media y eludir un mecanismo de protección sandbox a través de vectores desconocidos, según lo demostrado por ZDI durante una competición Pwn4Fun en CanSecWest 2014. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Internet Explorer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the ability to trick the broker into loading a malicious page in a privileged context. The issue lies in the implicit trust of navigating to localhost. • https://www.exploit-db.com/exploits/34010 http://twitter.com/thezdi/statuses/443810610958958592 http://www.pwn2own.com/2014/03/pwn2own-results-for-wednesday-day-one http://www.securityfocus.com/bid/67511 http://www.securitytracker.com/id/1030370 https://docs.microsoft.com/en-us/security-updates/securitybulletins/2014/ms14-035 •
CVE-2014-1753 – Microsoft Internet Explorer CAttrArray Use-After-Free Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2014-1753
Microsoft Internet Explorer 6 through 9 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, aka "Internet Explorer Memory Corruption Vulnerability." Microsoft Internet Explorer 6 hasta 9 permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (corrupción de memoria) a través de un sitio web manipulado, también conocido como "Vulnerabilidad de Corrupción de Memoria de Internet Explorer." This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Internet Explorer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of CAttrArray objects. By manipulating a document's elements an attacker can force a dangling pointer to be reused after it has been freed. • https://docs.microsoft.com/en-us/security-updates/securitybulletins/2014/ms14-018 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
