Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the webkit package.

For the stable distribution (lenny), these problems has been fixed in version 1.0.1-4+lenny2.
