CVSS v3.1 |
| Opera before 8.51, when running on Windows with Input Method Editor (IME) installed, allows remote attackers to cause a denial of service (persistent application crash) by bookmarking a site with a long title. |
| The International Domain Name (IDN) support in Opera 7.54 allows remote attackers to spoof domain names using punycode encoded domain names that are decoded in URLs and SSL certificates in a way that uses homograph characters from other character sets, which facilitates phishing attacks. |
| Opera 8.50 allows remote attackers to cause a denial of service (crash) via a Java applet with a large string argument to the removeMember JNI method for the com.opera.JSObject class. |
| Opera before 8.51 on Linux and Unix systems allows remote attackers to execute arbitrary code via shell metacharacters (backticks) in a URL that another product provides in a command line argument when launching Opera. |
| 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, probably before 7.50, sends Referer headers containing https:// URLs in requests for http:// URLs, which allows remote attackers to obtain potentially sensitive information by reading Referer log data. |
| 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. |
| Multiple unspecified vulnerabilities in Opera 8.50 on Linux and Windows have unknown impact and attack vectors, related to (1) " handling of must-revalidate cache directive for HTTPS pages" or (2) a "display issue with cookie comment encoding." |
| 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. |
| Unspecified "drag-and-drop vulnerability" in Opera Web Browser before 8.50 on Windows allows "unintentional file uploads." |
| Opera before 8.50 allows remote attackers to spoof the content type of files via a filename with a trailing "." (dot), which might allow remote attackers to trick users into processing dangerous content. |
| The Javascript engine in Opera 7.23 allows remote attackers to cause a denial of service (crash) by creating a new Array object with a large size value, then writing into that array. |
| Cross-site scripting (XSS) vulnerability in Opera 6.0 through 7.0 with automatic redirection disabled allows remote attackers to inject arbitrary web script or HTML via the HTTP Location header. |
| Opera allows remote attackers to cause a denial of service (invalid memory reference and application crash) via a web page or HTML email that contains a TBODY tag with a large COL SPAN value, as demonstrated by mangleme. |
| The PluginContext object of Opera 6.05 and 7.0 allows remote attackers to cause a denial of service (crash) via an HTTP request containing a long string that gets passed to the ShowDocument method. |
| Opera 7.54 and earlier uses kfmclient exec to handle unknown MIME types, which allows remote attackers to execute arbitrary code via a shortcut or launcher that contains an Exec entry. |
| Opera allows remote attackers to bypass intended cookie access restrictions on a web application via "%2e%2e" (encoded dot dot) directory traversal sequences in a URL, which causes Opera to send the cookie outside the specified URL subsets, e.g. to a vulnerable application that runs on the same server as the target application. |
| Opera 7.x up to 7.54, and possibly other versions, allows remote attackers to spoof arbitrary web sites by injecting content from one window into a target window whose name is known but resides in a different domain, as demonstrated using a pop-up window on a trusted web site, aka the "window injection" vulnerability. |
| Integer overflow in Opera 8.54 and earlier allows remote attackers to execute arbitrary code via a JPEG image with large height and width values, which causes less memory to be allocated than intended. |
| Integer signedness error in Opera before 8.54 allows remote attackers to execute arbitrary code via long values in a stylesheet attribute, which pass a length check. NOTE: a sign extension problem makes the attack easier with shorter strings. |
