NOTE: the vendor report...

CVE-2012-1251

Opera before 9.63 does not properly verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

CVE-2012-1924

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.

CVE-2012-1925

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.

CVE-2012-1926

Opera before 11.62 allows remote attackers to bypass the Same Origin Policy via the (1) history.pushState and (2) history.replaceState functions in conjunction with cross-domain frames, leading to unintended read access to history.state information.

CVE-2012-1927

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.

CVE-2012-1928

Opera before 11.62 allows remote attackers to spoof the address field by triggering a page reload followed by a redirect to a different domain.

CVE-2012-1929

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.

CVE-2012-1930

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.

CVE-2012-1931

Opera before 11.62 on UNIX, when used in conjunction with an unspecified printing application, allows local users to overwrite arbitrary files via a symlink attack on a temporary file during printing.

CVE-2012-3555

Opera before 11.65 does not ensure that keyboard sequences are associated with a visible window, which makes it easier for user-assisted remote attackers to conduct cross-site scripting (XSS) attacks or execute arbitrary code via a crafted web site, related to a "hidden keyboard navigation" issue.

CVE-2012-3556

Opera before 11.65 does not properly restrict the opening of a pop-up window in response to the first click of a double-click action, which makes it easier for user-assisted remote attackers to conduct cross-site scripting (XSS) attacks or execute arbitrary code via a crafted web site.

CVE-2012-3557

Opera before 11.65 does not properly restrict the reading of JSON strings, which allows remote attackers to perform cross-domain loading of JSON resources and consequently obtain sensitive information via a crafted web site.

CVE-2012-3558

Opera before 11.65 does not ensure that the address field corresponds to the displayed web page during unusually timed changes to this field, which makes it easier for user-assisted remote attackers to conduct spoofing attacks via vectors involving navigation, reloads, and redirects.

CVE-2012-3559

Unspecified vulnerability in Opera before 12.00 on Mac OS X has unknown impact and attack vectors, related to a "moderate severity issue."

CVE-2012-3560

Opera before 11.65 does not ensure that the address field corresponds to the displayed web page during blocked navigation, which makes it easier for remote attackers to conduct spoofing attacks by detecting and preventing attempts to load a different web page.

CVE-2012-3561

Opera before 11.64 does not properly allocate memory for URL strings, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted string.

CVE-2012-3562

Opera before 12.00 Beta allows user-assisted remote attackers to cause a denial of service (application crash) via a crafted web page that is not properly handled during a reload, as demonstrated by a "multiple origin camera test" page.

CVE-2012-3563

Opera before 12.00 Beta allows remote attackers to cause a denial of service (application crash) via a web page that contains invalid character encodings.

CVE-2012-3564

Opera before 12.00 Beta allows remote attackers to cause a denial of service (application hang) via an absolutely positioned wrap=off TEXTAREA element located next to an "overflow: auto" block element.

CVE-2012-3565

Opera before 12.00 Beta allows remote attackers to cause a denial of service (application crash) via crafted characters in domain names, as demonstrated by "IDNA2008 tests."

CVE-2012-3566

Opera before 12.00 Beta allows user-assisted remote attackers to cause a denial of service (application hang) via JavaScript code that changes a form before submission.

CVE-2012-3567

Opera before 12.00 Beta allows remote attackers to cause a denial of service (memory consumption or application hang) via an IFRAME element that uses the src="#" syntax to embed a parent document.

CVE-2012-3568

Opera before 12.00 Beta allows remote attackers to cause a denial of service (application crash) via crafted WebGL content, as demonstrated by a codeflow.org WebGL demo.

CVE-2012-4010

Opera before 11.60 allows remote attackers to spoof the address bar via unspecified homograph characters, a different vulnerability than CVE-2010-2660.

CVE-2012-4142

Opera before 12.01 on Windows and UNIX, and before 11.66 and 12.x before 12.01 on Mac OS X, ignores some characters in HTML documents in unspecified circumstances, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted document.

CVE-2012-4143

Opera before 12.01 on Windows and UNIX, and before 11.66 and 12.x before 12.01 on Mac OS X, allows user-assisted remote attackers to trick users into downloading and executing arbitrary files via a small window for the download dialog, a different vulnerability than CVE-2012-1924.

CVE-2012-4144

Opera before 12.01 on Windows and UNIX, and before 11.66 and 12.x before 12.01 on Mac OS X, does not properly escape characters in DOM elements, which makes it easier for remote attackers to bypass cross-site scripting (XSS) protection mechanisms via a crafted HTML document.

CVE-2012-4145

Unspecified vulnerability in Opera before 12.01 on Windows and UNIX, and before 11.66 and 12.x before 12.01 on Mac OS X, has unknown impact and attack vectors, related to a "low severity issue."

CVE-2012-4146

Opera before 12.01 allows remote attackers to cause a denial of service (application crash) via a crafted web site, as demonstrated by the Lenovo "Shop now" page.
