https://notcve.org/view.php?id=CVE-2012-1523
Microsoft Internet Explorer 6 through 8 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing a deleted object, aka "Center Element Remote Code Execution Vulnerability." Microsoft Internet Explorer v6 hasta v8 no gestionan de forma correcta objetos en memoria, lo que permite a atacantes remotos ejecutar código accediendo a un objeto eliminado, también conocida como "Center Element Remote Code Execution Vulnerability." • http://www.us-cert.gov/cas/techalerts/TA12-164A.html https://docs.microsoft.com/en-us/security-updates/securitybulletins/2012/ms12-037 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A15579 • CWE-94: Improper Control of Generation of Code ('Code Injection') •
CVE-2012-1877 – Microsoft Internet Explorer Title Element Change Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2012-1877
Microsoft Internet Explorer 6 through 9 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing a deleted object, aka "Title Element Change Remote Code Execution Vulnerability." Microsoft Internet Explorer 6 hasta 9 no maneja adecuadamente objetos en memoria, lo que permite a atacantes remotos ejecutar código de su elección mediante el acceso a un objeto borrado, también conocido como "vulnerabilidad de ejecución remota de código de cambio de título de elemento". 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 in the 'onpropertychange' user callback function for the document.title. If the function changes the document in the callback function by using, for example, a document.write call, this can result in a use-after-free vulnerability. • http://www.us-cert.gov/cas/techalerts/TA12-164A.html https://docs.microsoft.com/en-us/security-updates/securitybulletins/2012/ms12-037 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A15472 • CWE-94: Improper Control of Generation of Code ('Code Injection') •
CVE-2012-0217 – FreeBSD - Intel SYSRET Privilege Escalation
https://notcve.org/view.php?id=CVE-2012-0217
The x86-64 kernel system-call functionality in Xen 4.1.2 and earlier, as used in Citrix XenServer 6.0.2 and earlier and other products; Oracle Solaris 11 and earlier; illumos before r13724; Joyent SmartOS before 20120614T184600Z; FreeBSD before 9.0-RELEASE-p3; NetBSD 6.0 Beta and earlier; Microsoft Windows Server 2008 R2 and R2 SP1 and Windows 7 Gold and SP1; and possibly other operating systems, when running on an Intel processor, incorrectly uses the sysret path in cases where a certain address is not a canonical address, which allows local users to gain privileges via a crafted application. NOTE: because this issue is due to incorrect use of the Intel specification, it should have been split into separate identifiers; however, there was some value in preserving the original mapping of the multi-codebase coordinated-disclosure effort to a single identifier. El modo de usuario Scheduler en el núcleo en Microsoft Windows Server v2008 R2 y R2 SP1 y Windows v7 Gold y SP1 sobre la plataforma x64 no maneja adecuadamente solicitudes del sistema, lo que permite a usuarios locales obtener privilegios a través de una aplicación modificada, también conocida como "vulnerabilidad de corrupción de memoria de modo de usuario Scheduler". It was found that the Xen hypervisor implementation as shipped with Red Hat Enterprise Linux 5 did not properly restrict the syscall return addresses in the sysret return path to canonical addresses. An unprivileged user in a 64-bit para-virtualized guest, that is running on a 64-bit host that has an Intel CPU, could use this flaw to crash the host or, potentially, escalate their privileges, allowing them to execute arbitrary code at the hypervisor level. • https://www.exploit-db.com/exploits/46508 https://www.exploit-db.com/exploits/28718 https://www.exploit-db.com/exploits/20861 http://blog.illumos.org/2012/06/14/illumos-vulnerability-patched http://blog.xen.org/index.php/2012/06/13/the-intel-sysret-privilege-escalation http://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2012-003.txt.asc http://lists.xen.org/archives/html/xen-announce/2012-06/msg00001.html http://lists.xen.org/archives/html/xen-devel/2012-06 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2012-1876 – Microsoft Internet Explorer Fixed Table Colspan Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2012-1876
Microsoft Internet Explorer 6 through 9, and 10 Consumer Preview, does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by attempting to access a nonexistent object, leading to a heap-based buffer overflow, aka "Col Element Remote Code Execution Vulnerability," as demonstrated by VUPEN during a Pwn2Own competition at CanSecWest 2012. Consumer Preview de Microsoft Internet Explorer versión 6 hasta la versión 9 y versión 10 , no maneja apropiadamente los objetos en la memoria, lo que permite a los atacantes remotos ejecutar código arbitrario mediante el intento de acceder a un objeto inexistente, lo que conlleva a un desbordamiento del búfer en la región Heap de la memoria, también se conoce como "Col Element Remote Code Execution Vulnerability" demostrado por VUPEN durante una competición Pwn2Own en CanSecWest 2012. 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 way Internet Explorer handles dynamically changed colspans on a column in a table with the table-layout:fixed style. If the colspan is increased after initial creation it will result in a heap overflow. • https://www.exploit-db.com/exploits/20174 https://www.exploit-db.com/exploits/24017 https://www.exploit-db.com/exploits/34815 https://www.exploit-db.com/exploits/33944 https://www.exploit-db.com/exploits/35273 https://github.com/WizardVan/CVE-2012-1876 https://github.com/ExploitCN/CVE-2012-1876-win7_x86_and_win7x64 http://arstechnica.com/business/news/2012/03/ie-9-on-latest-windows-gets-stomped-at-hacker-contest.ars http://pwn2own.zerodayinitiative.com/status.html http: • CWE-94: Improper Control of Generation of Code ('Code Injection') •

The Network Threat Protection module in the Manager component in Symantec Endpoint Protection (SEP) 11.0.600x through 11.0.700x on Windows Server 2003 allows remote attackers to cause a denial of service (web-server outage, or daemon crash or hang) via a flood of packets that triggers automated blocking of network traffic. El módulo Network Threat Protection en Manager component en Symantec Endpoint Protection (SEP) v11.0.600x hasta v11.0.700x en Windows Server 2003 permite a atacantes remotos causar una denegación de servicio (bloqueo de la aplicación) a través de una inundación de paquetes automatizados. • http://osvdb.org/82147 http://secunia.com/advisories/49221 http://www.kb.cert.org/vuls/id/149070 http://www.securityfocus.com/bid/50358 http://www.securitytracker.com/id?1027092 http://www.symantec.com/security_response/securityupdates/detail.jsp?fid=security_advisory&pvid=security_advisory&year=2012&suid=20120522_00 •
