CVE-2012-6467 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-6467):
  Opera before 12.10 follows Internet shortcuts that are referenced by a (1)
  IMG element or (2) other inline element, which makes it easier for remote
  attackers to conduct phishing attacks via a crafted web site, as exploited
  in the wild in November 2012.

CVE-2012-6466 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-6466):
  Opera before 12.10 does not properly handle incorrect size data in a WebP
  image, which allows remote attackers to obtain potentially sensitive
  information from process memory by using a crafted image as the fill pattern
  for a canvas.

CVE-2012-6465 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-6465):
  Opera before 12.10 allows remote attackers to execute arbitrary code or
  cause a denial of service (application crash) via a malformed SVG image.

CVE-2012-6464 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-6464):
  Cross-site scripting (XSS) vulnerability in Opera before 12.10 allows remote
  attackers to inject arbitrary web script or HTML via crafted JavaScript code
  that overrides methods of unspecified native objects in documents that have
  different origins.

CVE-2012-6463 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-6463):
  Cross-site scripting (XSS) vulnerability in Opera before 12.10 allows remote
  attackers to inject arbitrary web script or HTML via vectors involving an
  unspecified sequence of loading of documents and loading of data: URLs.

CVE-2012-6462 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-6462):
  Opera before 12.10 does not properly implement the Cross-Origin Resource
  Sharing (CORS) specification, which allows remote attackers to bypass
  intended page-content restrictions via a crafted request.

CVE-2012-6461 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-6461):
  The X.509 certificate-validation functionality in the https implementation
  in Opera before 12.10 allows remote attackers to trigger a false indication
  of successful revocation-status checking by causing a failure of a single
  checking service.
