Unspecified vulnerability in Opera before 9.5 allows remote attackers to read cross-domain images via HTML CANVAS elements that use the images as patterns.

Unspecified vulnerability in Opera before 9.5 allows remote attackers to spoof the contents of trusted frames on the same parent page by modifying the location, which can facilitate phishing attacks.

Opera before 9.27 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted scaled image pattern in an HTML CANVAS element, which triggers memory corruption.

Opera before 9.26 allows user-assisted remote attackers to read arbitrary files by tricking a user into typing the characters of the target filename into a file input.

Opera before 9.26 allows user-assisted remote attackers to execute arbitrary script via images that contain custom comments, which are treated as script when the user displays the image properties.

Opera before 9.26 allows remote attackers to "bypass sanitization filters" and conduct cross-site scripting (XSS) attacks via crafted attribute values in an XML document, which are not properly handled during DOM presentation.

Opera before 9.25 allows remote attackers to conduct cross-domain scripting attacks via unknown vectors related to plug-ins.

Unspecified vulnerability in Opera before 9.25 allows remote attackers to execute arbitrary code via crafted TLS certificates.

The rich text editing functionality in Opera before 9.25 allows remote attackers to conduct cross-domain scripting attacks by using designMode to modify contents of pages in other domains.

Opera before 9.25 allows remote attackers to obtain potentially sensitive memory contents via a crafted bitmap (BMP) file, as demonstrated using a CANVAS element and JavaScript in an HTML document for copying these contents from 9.50 beta, a related issue to CVE-2008-0420.

Unspecified vulnerability in Adobe Flash Player 9.0.47.0 and earlier, when running on Opera before 9.24 on Mac OS X, has unknown "Highly Severe" impact and unknown attack vectors.

Unspecified vulnerability in Opera before 9.24 allows remote attackers to overwrite functions on pages from other domains and bypass the same-origin policy via unknown vectors.

Unspecified vulnerability in Opera before 9.24, when using an "external" newsgroup or e-mail client, allows remote attackers to execute arbitrary commands via unknown vectors.

Sun Java Runtime Environment (JRE) in JDK and JRE 6 Update 2 and earlier, JDK and JRE 5.0 Update 12 and earlier, SDK and JRE 1.4.2_15 and earlier, and SDK and JRE 1.3.1_20 and earlier, when Firefox or Opera is used, allows remote attackers to violate the security model for JavaScript outbound connections via a multi-pin DNS rebinding attack dependent on the LiveConnect API, in which JavaScript download relies on DNS resolution by the browser, but JavaScript socket operations rely on separate DNS resolution by a Java Virtual Machine (JVM), a different issue than CVE-2007-5273. NOTE: this is similar to CVE-2007-5232.

Opera before 9.23 allows remote attackers to execute arbitrary code via crafted Javascript that triggers a "virtual function call on an invalid pointer."

Use-after-free vulnerability in the BitTorrent support in Opera before 9.22 allows user-assisted remote attackers to execute arbitrary code via a crafted header in a torrent file, which leaves a dangling pointer to an invalid object.

Buffer overflow in the transfer manager in Opera before 9.21 for Windows allows user-assisted remote attackers to execute arbitrary code via a crafted torrent file. NOTE: due to the lack of details, it is not clear if this is the same issue as CVE-2007-2274.

Adobe Macromedia Flash Player 7 and 9, when used with Opera before 9.20 or Konqueror before 20070613, allows remote attackers to obtain sensitive information (browser keystrokes), which are leaked to the Flash Player applet.

Opera allows remote attackers to cause a denial of service (application crash) via a web page that contains a large number of nested marquee tags, a related issue to CVE-2006-2723.

The Javascript SVG support in Opera before 9.10 does not properly validate object types in a createSVGTransformFromMatrix request, which allows remote attackers to execute arbitrary code via JavaScript code that uses an invalid object in this request that causes a controlled pointer to be referenced during the virtual function call.
