CVE-2011-0133

TITLE

plural Apple Product WebKit Vulnerable to arbitrary code execution

DESCRIPTION

WebKit, as used in Apple iTunes before 10.2 on Windows, does not properly access glyph data during layout actions for floating blocks associated with pseudo-elements, which allows man-in-the-middle attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via vectors related to iTunes Store browsing, a different vulnerability than other CVEs listed in APPLE-SA-2011-03-02-1. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Safari's Webkit. 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 the application handles floating blocks in certain situations. When performing layout operations for a floating block produced by a pseudo-element, the application will attempt to access glyph data that hasn't been fully assigned into the glyph data hashmap. Due to this type being incomplete, this can lead to code execution under the context of the application. WebKit is prone to multiple memory-corruption vulnerabilities. An attacker may exploit these issues by enticing victims into viewing a malicious webpage. This BID is being retired.

For more information: SA40302 2) An array indexing error in the CoreGraphics library (ImageIO) when processing the International Color Consortium (ICC) profile within a JPEG image can be exploited to corrupt heap-based memory. 3) An error in the libTIFF library when handling JPEG encoded TIFF images can be exploited to cause a buffer overflow. 4) A boundary error in the libTIFF library when handling CCITT Group 4 encoded TIFF images. For more information: SA43593 5) A double free error in the libxml library when handling XPath expressions. For more information: SA42721 6) An error exists in the libxml library when traversing the XPath. 8) An error in the WebKit component when elements are being appended to the DOM tree during the display of an error message can be exploited to access a freed element via a specially crafted document. 9) An error in the WebKit component when handling a DOM level 2 range object can be exploited to corrupt memory by manipulating the DOM via an event listener. 10) A use-after-free error in the "setOuterText()" method in the htmlelement library (WebKit) when tracking DOM manipulations can be exploited to dereference freed memory. 11) A use-after-free error in the WebKit component when promoting a run-in element can be exploited to dereference freed memory. 13) An error in the WebKit component when parsing a Root HTMLBRElement element can be exploited to call an unmapped dangling pointer. 14) An error in the Javascript array "sort()" method (WebKit) can be exploited to manipulate elements outside of the array's boundary.
