Opera before 11.60 allows remote attackers to cause a denial of service (CPU and memory consumption) via unspecified content on a web page, as demonstrated by a page under the cisco.com home page.

Unspecified vulnerability in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via vectors involving SVG animation.

The Cascading Style Sheets (CSS) implementation in Opera before 11.11 does not properly handle the column-count property, which allows remote attackers to cause a denial of service (infinite repaint loop and application hang) via a web page, as demonstrated by an unspecified Wikipedia page.

Unspecified vulnerability in Opera before 11.50 allows remote attackers to cause a denial of service (memory consumption) via unknown content on a web page, as demonstrated by test262.ecmascript.org.
