Microsoft Internet Explorer 8 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing an object that (1) was not properly initialized or (2) is deleted, leading to memory corruption, aka "Uninitialized Memory Corruption Vulnerability," a different vulnerability than CVE-2009-3671, CVE-2009-3674, CVE-2010-0245, and CVE-2010-0246.

Race condition in Microsoft Internet Explorer 6, 7, and 8 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via vectors related to an object in memory, aka "Race Condition Memory Corruption Vulnerability."

Microsoft Internet Explorer 6 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing an object that (1) was not properly initialized or (2) is deleted, leading to memory corruption, aka "Uninitialized Memory Corruption Vulnerability."

Microsoft Internet Explorer 6, 7, and 8 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing an object that (1) was not properly initialized or (2) is deleted, leading to memory corruption, aka "Uninitialized Memory Corruption Vulnerability."

WebKit in Apple Safari before 5.0.1 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1.1 on Mac OS X 10.4; and webkitgtk before 1.2.6; allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted regular expression.

Integer signedness error in WebKit in Apple Safari before 5.0.1 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1.1 on Mac OS X 10.4, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors involving a JavaScript array index.

WebKit in Apple Safari before 5.0.1 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1.1 on Mac OS X 10.4; and webkitgtk before 1.2.6; does not properly handle just-in-time (JIT) compiled JavaScript stubs, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted HTML document, related to a "reentrancy issue."

Heap-based buffer overflow in WebKit in Apple Safari before 5.0.1 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1.1 on Mac OS X 10.4, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a JavaScript string object.
