Debian Bug : 532724 532725 534946 535793 538346
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 web sites 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 web sites 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 web sites via vectors involving a CANVAS element and
redirection, related to a "cross-site image capture issue."
CVE-2009-1681
WebKit does not prevent web sites 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.
For the stable distribution (lenny), these problems has been fixed in
version 1.0.1-4+lenny2.
For the testing distribution (squeeze) and the unstable distribution
(sid), these problems have been fixed in version 1.1.16-1.
We recommend that you upgrade your webkit package.
