webkit - several vulnerabilities

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.
