CVSS v3.1 |
| Opera allows remote attackers to cause a denial of service (application crash) via a web page that contains a large number of nested marquee tags, a related issue to CVE-2006-2723. |
| Opera executes DOM calls in response to a javascript: URI in the target attribute of a submit element within a form contained in an inline PDF file, which might allow remote attackers to bypass intended Adobe Acrobat JavaScript restrictions on accessing the document object, as demonstrated by a web site that permits PDF uploads by untrusted users, and therefore has a shared document.domain between the web site and this javascript: URI. NOTE: the researcher reports that Adobe's position is "a PDF file is active content." |
| Opera before 10.00 does not properly handle a (1) '\0' character or (2) invalid wildcard character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority. |
| 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. |
| Opera displays a cached certificate for a (1) 4xx or (2) 5xx CONNECT response page returned by a proxy server, which allows man-in-the-middle attackers to spoof an arbitrary https site by letting a browser obtain a valid certificate from this site during one request, and then sending the browser a crafted 502 response page upon a subsequent request. |
| Opera 9.10 Final allows remote attackers to bypass the Fraud Protection mechanism by adding certain characters to the end of a domain name, as demonstrated by the "." and "/" characters, which is not caught by the blacklist filter. |
| 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. |
| 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. |
| 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. |
| The FTP protocol implementation in Opera 9.10 allows remote attackers to allows remote servers to force the client to connect to other servers, perform a proxied port scan, or obtain sensitive information by specifying an alternate server address in an FTP PASV response. |
| The HTML parsing engine in Opera before 9.63 allows remote attackers to execute arbitrary code via crafted web pages that trigger an invalid pointer calculation and heap corruption. |
| Opera 7.50 and earlier allows remote web sites to provide a "Shortcut Icon" (favicon) that is wider than expected, which could allow the web sites to spoof a trusted domain and facilitate phishing attacks using a wide icon and extra spaces. |
| Opera Browser 7.23, and other versions before 7.50, updates the address bar as soon as the user clicks a link, which allows remote attackers to redirect to other sites via the onUnload attribute. |
| Opera offers an Open button to verify that a user wishes to execute a downloaded file, which allows user-assisted remote attackers to construct a race condition that tricks a user into clicking Open via a request for a different mouse or keyboard action very shortly before the Open dialog appears. NOTE: this is a different issue than CVE-2005-2407. |
| Opera 7.54 and earlier does not properly validate base64 encoded binary data in a data: (RFC 2397) URL, which causes the URL to be obscured in a download dialog, which may allow remote attackers to trick users into executing arbitrary code. |
| Opera 7.54 and earlier on Gentoo Linux uses an insecure path for plugins, which could allow local users to gain privileges by inserting malicious libraries into the PORTAGE_TMPDIR (portage) temporary directory. |
| Opera 8 Beta 3, when using first-generation vetted digital certificates, displays the Organizational information of an SSL certificate, which is easily spoofed and can facilitate phishing attacks. |
| The XMLHttpRequest object in Opera 8.0 Final Build 1095 allows remote attackers to bypass access restrictions and perform unauthorized actions on other domains via a redirect. |
| Opera 8.01 allows remote attackers to cause a denial of service (CPU consumption) via a crafted JPEG image, as demonstrated using random.jpg. |
| Opera Web Browser 8.50 and 8.0 through 8.0.2 allows remote attackers to spoof the URL in the status bar via the title in an image in a link to a trusted site within a form to the malicious site. |
