Unspecified vulnerability in Opera before 11.50 allows remote attackers to cause a denial of service (application hang) via unknown content on a web page, as demonstrated by domiteca.com.

The SVG implementation in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via vectors involving a path on which many characters are drawn.

The Array.prototype.join method in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via a non-array object that contains initial holes.

Unspecified vulnerability in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via unknown content on a web page, as demonstrated by progorod.ru.

Unspecified vulnerability in the printing functionality in Opera before 11.50 allows user-assisted remote attackers to cause a denial of service (application crash) via a crafted web page.

Unspecified vulnerability in Opera before 11.50 has unknown impact and attack vectors, related to a "moderately severe issue."

Opera before 11.50 does not properly restrict data: URIs, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted web site.

Opera before 11.50 allows remote attackers to cause a denial of service (disk consumption) via invalid URLs that trigger creation of error pages.

The VEGAOpBitmap::AddLine function in Opera before 10.61 does not properly initialize memory during processing of the SIZE attribute of a SELECT element, which allows remote attackers to trigger an invalid memory write operation, and consequently cause a denial of service (application crash) or possibly execute arbitrary code, via a large integer attribute value.
