Opera before 11.62 on Mac OS X allows remote attackers to spoof the address field and security dialogs via crafted styling that causes page content to be displayed outside of the intended content area.

Opera before 11.62 on UNIX uses world-readable permissions for temporary files during printing, which allows local users to obtain sensitive information by reading these files.

Opera before 11.62 does not ensure that a dialog window is placed on top of content windows, which makes it easier for user-assisted remote attackers to trick users into downloading and executing arbitrary files via a download dialog located under other windows.

Opera before 11.62 allows user-assisted remote attackers to trick users into downloading and executing arbitrary files via a small window for the download dialog.

Opera before 11.62 allows remote attackers to spoof the address field by triggering the launch of a dialog window associated with a different domain.

Multiple integer overflows in Opera 11.60 and earlier allow remote attackers to cause a denial of service (application crash) via a large integer argument to the (1) Int32Array, (2) Float32Array, (3) Float64Array, (4) Uint32Array, (5) Int16Array, or (6) ArrayBuffer function. NOTE: the vendor reportedly characterizes this as "a stability issue, not a security issue."

Opera before 10.61 does not properly suppress clicks on download dialogs that became visible after a recent tab change, which allows remote attackers to conduct clickjacking attacks, and consequently execute arbitrary code, via vectors involving (1) closing a tab or (2) hiding a tab, a related issue to CVE-2005-2407.

Heap-based buffer overflow in Opera before 10.61 allows remote attackers to execute arbitrary code or cause a denial of service (application crash or hang) via vectors related to HTML5 canvas painting operations that occur during the application of transformations.

The news-feed preview feature in Opera before 10.61 does not properly remove scripts, which allows remote attackers to force subscriptions to arbitrary feeds via crafted content.

Unspecified vulnerability in Opera before 10.61 allows remote attackers to cause a denial of service (CPU consumption and application hang) via an animated PNG image.
