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

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.

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.

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.

Integer signedness error in Opera before 8.54 allows remote attackers to execute arbitrary code via long values in a stylesheet attribute, which pass a length check. NOTE: a sign extension problem makes the attack easier with shorter strings.

The mail client in Opera before 8.50 opens attached files from the user's cache directory without warning the user, which might allow remote attackers to inject arbitrary web script and spoof attachment filenames.
