CVE-2012-3567 1 Opera 1 Opera Browser 2017-08-29 5.0 MEDIUM N/A
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-2012-1003 1 Opera 1 Opera Browser 2017-08-29 5.0 MEDIUM N/A
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."
CVE-2012-3564 1 Opera 1 Opera Browser 2017-08-29 5.0 MEDIUM N/A
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-2012-3566 1 Opera 1 Opera Browser 2017-08-29 4.3 MEDIUM N/A
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-2012-3563 1 Opera 1 Opera Browser 2017-08-29 5.0 MEDIUM N/A
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-2012-3562 1 Opera 1 Opera Browser 2017-08-29 4.3 MEDIUM N/A
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-2012-3568 1 Opera 1 Opera Browser 2017-08-29 5.0 MEDIUM N/A
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-2011-3388 1 Opera 1 Opera Browser 2017-08-29 4.3 MEDIUM N/A
Opera before 11.51 allows remote attackers to cause an insecure site to appear secure or trusted via unspecified actions related to Extended Validation and loading content from trusted sources in an unspecified sequence that causes the address field and page information dialog to contain security information based on the trusted site, instead of the insecure site.
CVE-2011-2640 1 Opera 1 Opera Browser 2017-08-29 5.0 MEDIUM N/A
Opera before 11.10 allows remote attackers to cause a denial of service (application crash) via an HTML document that has an empty parameter value for an embedded Java applet.
CVE-2011-2609 1 Opera 1 Opera Browser 2017-08-29 4.3 MEDIUM N/A
Opera before 11.50 does not properly restrict data: URIs, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted web site.
CVE-2011-1337 1 Opera 1 Opera Browser 2017-08-17 4.3 MEDIUM N/A
Opera before 11.50 allows remote attackers to cause a denial of service (disk consumption) via invalid URLs that trigger creation of error pages.
CVE-2010-1349 2 Microsoft, Opera 2 Windows, Opera Browser 2017-08-17 10.0 HIGH N/A
Integer overflow in Opera 10.10 through 10.50 allows remote attackers to execute arbitrary code via a large Content-Length value, which triggers a heap overflow.
CVE-2009-2068 1 Opera 1 Opera 2017-08-17 5.8 MEDIUM N/A
Google Chrome detects http content in https web pages only when the top-level frame uses https, which allows man-in-the-middle attackers to execute arbitrary web script, in an https site's context, by modifying an http page to include an https iframe that references a script file on an http site, related to "HTTP-Intended-but-HTTPS-Loadable (HPIHSL) pages."
CVE-2009-2063 1 Opera 1 Opera Browser 2017-08-17 6.8 MEDIUM N/A
Opera, possibly before 9.25, processes a 3xx HTTP CONNECT response before a successful SSL handshake, which allows man-in-the-middle attackers to execute arbitrary web script, in an https site's context, by modifying this CONNECT response to specify a 302 redirect to an arbitrary https web site.
CVE-2008-4293 2 Microsoft, Opera 2 Windows, Opera 2017-08-08 10.0 HIGH N/A
Unspecified vulnerability in Opera before 9.52 on Windows, when registered as a protocol handler, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unknown vectors in which Opera is launched by other applications.
CVE-2008-4199 1 Opera 1 Opera Browser 2017-08-08 5.0 MEDIUM N/A
Opera before 9.52 does not prevent use of links from web pages to feed source files on the local disk, which might allow remote attackers to determine the validity of local filenames via vectors involving "detection of JavaScript events and appropriate manipulation."
CVE-2008-4200 1 Opera 1 Opera Browser 2017-08-08 6.4 MEDIUM N/A
Opera before 9.52 does not ensure that the address field of a news feed represents the feed's actual URL, which allows remote attackers to change this field to display the URL of a page containing web script controlled by the attacker.
CVE-2008-4697 1 Opera 1 Opera Browser 2017-08-08 4.3 MEDIUM N/A
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.
CVE-2008-4698 1 Opera 1 Opera Browser 2017-08-08 5.8 MEDIUM N/A
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.
CVE-2008-4794 1 Opera 1 Opera 2017-08-08 9.3 HIGH N/A
Opera before 9.62 allows remote attackers to execute arbitrary commands via the History Search results page, a different vulnerability than CVE-2008-4696.
