WebKit before r41741, as used in Apple iPhone OS 1.0 through 2.2.1, iPhone OS for iPod touch 1.1 through 2.2.1, Safari, and other software, allows remote attackers to cause a denial of service (memory consumption or device reset) via a web page containing an HTMLSelectElement object with a large length attribute, related to the length property of a Select object.

Various bugs in webkit have been fixed. The CVE id's are :

Several vulnerabilities have been discovered in WebKit, a Web content engine library for Gtk+. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2009-0945     Array index error in the insertItemBefore method in     WebKit, allows remote attackers to execute arbitrary     code via a document with a SVGPathList data structure     containing a negative index in the SVGTransformList,     SVGStringList, SVGNumberList, SVGPathSegList,     SVGPointList, or SVGLengthList SVGList object, which     triggers memory corruption.

  - CVE-2009-1687     The JavaScript garbage collector in WebKit does not     properly handle allocation failures, which allows remote     attackers to execute arbitrary code or cause a denial of     service (memory corruption and application crash) via a     crafted HTML document that triggers write access to an     'offset of a NULL pointer.'

  - CVE-2009-1690     Use-after-free vulnerability in WebKit, 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.'

  - CVE-2009-1698     WebKit 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.

  - CVE-2009-1711     WebKit does not properly initialize memory for Attr DOM     objects, which allows remote attackers to execute     arbitrary code or cause a denial of service (application     crash) via a crafted HTML document.

  - CVE-2009-1712     WebKit does not prevent remote loading of local Java     applets, which allows remote attackers to execute     arbitrary code, gain privileges, or obtain sensitive     information via an APPLET or OBJECT element.

  - CVE-2009-1725     WebKit do not properly handle numeric character     references, which allows remote attackers to execute     arbitrary code or cause a denial of service (memory     corruption and application crash) via a crafted HTML     document.

  - CVE-2009-1714     Cross-site scripting (XSS) vulnerability in Web     Inspector in WebKit allows user-assisted remote     attackers to inject arbitrary web script or HTML, and     read local files, via vectors related to the improper     escaping of HTML attributes.

  - CVE-2009-1710     WebKit allows remote attackers to spoof the browser's     display of the host name, security indicators, and     unspecified other UI elements via a custom cursor in     conjunction with a modified CSS3 hotspot property.

  - CVE-2009-1697     CRLF injection vulnerability in WebKit allows remote     attackers to inject HTTP headers and bypass the Same     Origin Policy via a crafted HTML document, related to     cross-site scripting (XSS) attacks that depend on     communication with arbitrary websites on the same server     through use of XMLHttpRequest without a Host header.

  - CVE-2009-1695     Cross-site scripting (XSS) vulnerability in WebKit     allows remote attackers to inject arbitrary web script     or HTML via vectors involving access to frame contents     after completion of a page transition.

  - CVE-2009-1693     WebKit allows remote attackers to read images from     arbitrary websites via a CANVAS element with an SVG     image, related to a 'cross-site image capture issue.'

  - CVE-2009-1694     WebKit does not properly handle redirects, which allows     remote attackers to read images from arbitrary websites     via vectors involving a CANVAS element and redirection,     related to a 'cross-site image capture issue.'

  - CVE-2009-1681     WebKit does not prevent websites from loading     third-party content into a subframe, which allows remote     attackers to bypass the Same Origin Policy and conduct     'clickjacking' attacks via a crafted HTML document.

  - CVE-2009-1684     Cross-site scripting (XSS) vulnerability in WebKit     allows remote attackers to inject arbitrary web script     or HTML via an event handler that triggers script     execution in the context of the next loaded document.

  - CVE-2009-1692     WebKit allows remote attackers to cause a denial of     service (memory consumption or device reset) via a web     page containing an HTMLSelectElement object with a large     length attribute, related to the length property of a     Select object.

The version of Google Chrome installed on the remote host is earlier than 2.0.172.37.  Such versions are reportedly affected by multiple issues :

  - A heap overflow exists when evaluating specially crafted     regular expressions in JavaScript. This could lead to a     denial of service or the execution of arbitrary code     within the Google Chrome sandbox. (Issue 14719)

  - A memory corruption issue exists in the renderer process     that could cause a denial of service or possibly allow     arbitrary code execution with the privileges of the     logged on user. (CVE-2009-2556)

  - Creating a Select object with a very large length can     result in memory exhaustion, causing a denial of service.

Versions of Firefox 3.x prior to 3.0.5 are affected by the following security issues : 

 - There are several stability bugs in the browser engine that may lead to crashes with evidence of memory corruption. (MFSA 2008-60)
 - XBL bindings can be used to read data from other domains. (MFSA 2008-61)
 - The feed preview still allows for JavaScript privilege escalation. (MFSA 2008-62)
 - Sensitive data may be disclosed in an XHR response when an XMLHttpRequest is made to a same-origin resource, which 302 redirects to a resource in a different domain. (MFSA 2008-64)
 - A website may be able to access a limited amount of data from a different domain by loading a same-domain JavaScript URL which redirects to an off-domain target resource containing data that is not parsable as JavaScript. (MFSA 2008-65)
 - Errors arise when parsing URLs with leading whitespace and control characters. (MFSA 2008-66)
 - An escaped null byte is ignored by the CSS parser and treated as if it was not present in the CSS input string. (MFSA 2008-67)
 - XSS and JavaScript privilege escalation are possible. (MFSA 2008-68)
 - XSS vulnerabilities in SessionStore may allow for violating the browser's same-origin policy and performing an XSS attack or running arbitrary JavaScript with chrome privileges. (MFSA 2008-69)
 - A denial of service issue when the application handles a maliciously crafted webpage containing a 'HTMLSelectElement' object with a large length attribute.

The installed version of Firefox is earlier than 2.0.0.19.  Such versions are potentially affected by the following security issues : 

 - There are several stability bugs in the browser engine that may lead to crashes with evidence of memory corruption. (MFSA 2008-60)
 - XBL bindings can be used to read data from other domains. (MFSA 2008-61)
 - The feed preview still allows for JavaScript privilege escalation. (MFSA 2008-62)
 - Sensitive data may be disclosed in an XHR response when an XMLHttpRequest is made to a same-origin resource, which 302 redirects to a resource in a different domain. (MFSA 2008-64)

 - XSS and JavaScript privilege escalation are possible. (MFSA 2008-68)
 - XSS vulnerabilities in SessionStore may allow for violating the browser's same-origin policy and performing an XSS attack or running arbitrary JavaScript with chrome privileges. (MFSA 2008-69) Note that Mozilla is not planning further security / stability updates for Firefox 2.x.
  - A denial of service issue when the application handles a maliciously crafted webpage containing a 'HTMLSelectElement' object with a large length attribute.
