Several vulnerabilities were discovered in the Chromium browser. The Common Vulnerabilities and Exposures project identifies the following problems:

• CVE-2011-2818

  Use-after-free vulnerability in Google Chrome allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to display box rendering.

• CVE-2011-2800

  Google Chrome allows remote attackers to obtain potentially sensitive information about client-side redirect targets via a crafted web site.

  Google Chrome does not properly track line boxes during rendering, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors that lead to a stale pointer.

Several unauthorised SSL certificates have been found in the wild issued for the DigiNotar Certificate Authority, obtained through a security compromise with said company. This update blacklists SSL certificates issued by DigiNotar-controlled intermediate CAs used by the Dutch PKIoverheid program.
