9.3CVE-2008-4197operaopera_browser
EPSS score
6.33%
Opera before 9.52 on Windows, Linux, FreeBSD, and Solaris, when processing custom shortcut and menu commands, can produce argument strings that contain uninitialized memory, which might allow user-assisted remote attackers to execute arbitrary code or conduct other attacks via vectors related to activation of a shortcut.
4.3CVE-2008-4697operaopera_browser
EPSS score
1.71%
The Fast Forward feature in Opera before 9.61, when a page is located in a frame, executes a javascript: URL in the context of the outermost page instead of the page that contains this URL, which allows remote attackers to conduct cross-site scripting (XSS) attacks.
5CVE-2008-4195operaopera_browser
EPSS score
1.96%
Opera before 9.52 does not properly restrict the ability of a framed web page to change the address associated with a different frame, which allows remote attackers to trigger the display of an arbitrary address in a frame via unspecified use of web script.
5CVE-2008-4198operaopera_browser
EPSS score
2.84%
Opera before 9.52, when rendering an http page that has loaded an https page into a frame, displays a padlock icon and offers a security information dialog reporting a secure connection, which might allow remote attackers to trick a user into performing unsafe actions on the http page.
5.8CVE-2008-4698operaopera_browser
EPSS score
1.74%
Opera before 9.61 does not properly block scripts during preview of a news feed, which allows remote attackers to create arbitrary new feed subscriptions and read the contents of arbitrary feeds.
4.3CVE-2008-4725operaopera_browser
EPSS score
4.89%
Cross-site scripting (XSS) vulnerability in Opera.dll in Opera 9.52 allows remote attackers to inject arbitrary web script or HTML via the query string, which is not properly escaped before storage in the History Search database (aka md.dat), a different vector than CVE-2008-4696. NOTE: some of these issues were addressed before 9.60.
5CVE-2008-7245operaopera_browser
EPSS score
6.26%
Opera 9.52 and earlier allows remote attackers to cause a denial of service (unusable browser) by calling the window.print function in a loop, aka a "printing DoS attack," possibly a related issue to CVE-2009-0821.
9.3CVE-2008-5680operaopera_browser
EPSS score
7.51%
Multiple buffer overflows in Opera before 9.63 might allow (1) remote attackers to execute arbitrary code via a crafted text area, or allow (2) user-assisted remote attackers to execute arbitrary code via a long host name in a file: URL. NOTE: this might overlap CVE-2008-5178.
7.8CVE-2008-5683operaopera_browser
EPSS score
1.47%
Unspecified vulnerability in Opera before 9.63 allows remote attackers to "reveal random data" via unknown vectors.
4.3CVE-2008-5681operaopera_browser
EPSS score
1.10%
Opera before 9.63 does not block unspecified "scripted URLs" during the feed preview, which allows remote attackers to read existing subscriptions and force subscriptions to arbitrary feed URLs.

EPSS score
2.53%
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.
5CVE-2012-1003operaopera_browser
EPSS score
1.14%
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."
6.8CVE-2012-1924operaopera_browser
EPSS score
2.30%
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.

EPSS score
2.70%
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.
6.8CVE-2012-1925operaopera_browser
EPSS score
2.32%
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.
4.6CVE-2012-1931operaopera_browser
EPSS score
0.38%
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.
5.8CVE-2012-1251operaopera_browser
EPSS score
0.60%
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.
4.6CVE-2012-1930operaopera_browser
EPSS score
0.38%
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.
