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 initialize a pointer during handling of a Cascading Style Sheets (CSS) attr function call with a large numerical argument, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted HTML document.

Use-after-free vulnerability in the JavaScript DOM 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 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) by destroying a document.body element that has an unspecified XML container with elements that support the dir attribute.

Cross-site scripting (XSS) vulnerability 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 allows remote attackers to inject arbitrary web script or HTML via vectors related to improper handling of Location and History objects.

The XSLT 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 redirects, which allows remote attackers to read XML content from arbitrary web pages via a crafted document.

Use-after-free vulnerability in WebKit, as used in Apple Safari before 4.0, iPhone OS 1.0 through 2.2.1, iPhone OS for iPod touch 1.1 through 2.2.1, Google Chrome 1.0.154.53, and possibly other products, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) by setting an unspecified property of an HTML tag that causes child elements to be freed and later accessed when an HTML error occurs, related to "recursion in certain DOM event handlers."

Array index error in the insertItemBefore method in WebKit, as used in Apple Safari before 3.2.3 and 4 Public Beta, iPhone OS 1.0 through 2.2.1, iPhone OS for iPod touch 1.1 through 2.2.1, Google Chrome Stable before 1.0.154.65, and possibly other products allows remote attackers to execute arbitrary code via a document with a SVGPathList data structure containing a negative index in the (1) SVGTransformList, (2) SVGStringList, (3) SVGNumberList, (4) SVGPathSegList, (5) SVGPointList, or (6) SVGLengthList SVGList object, which triggers memory corruption.

Cross-site scripting (XSS) vulnerability in Safari before 3.2.3, and 4 Public Beta, on Apple Mac OS X 10.5 before 10.5.7 and Windows allows remote attackers to inject arbitrary web script or HTML via a crafted feed: URL.
