CVE-2005-0235 1 Opera 1 Opera Browser 2023-12-10 5.0 MEDIUM N/A
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.
CVE-2005-2273 1 Opera 1 Opera Browser 2023-12-10 2.6 LOW N/A
Opera 7.x and 8 before 8.01 does not clearly associate a Javascript dialog box with the web page that generated it, which allows remote attackers to spoof a dialog box from a trusted site and facilitates phishing attacks, aka the "Dialog Origin Spoofing Vulnerability."
CVE-2005-3007 1 Opera 1 Opera Browser 2023-12-10 2.6 LOW N/A
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.
CVE-2005-0233 4 Mozilla, Omnigroup, Opera and 1 more 6 Camino, Firefox, Mozilla and 3 more 2023-12-10 7.5 HIGH N/A
The International Domain Name (IDN) support in Firefox 1.0, Camino .8.5, and Mozilla before 1.7.6 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.
CVE-2006-3331 1 Opera 1 Opera Browser 2023-12-10 5.0 MEDIUM N/A
Opera before 9.0 does not reset the SSL security bar after displaying a download dialog from an SSL-enabled website, which allows remote attackers to spoof a trusted SSL certificate from an untrusted website and facilitates phishing attacks.
CVE-2006-3198 1 Opera 1 Opera Browser 2023-12-10 7.5 HIGH N/A
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.
CVE-2004-2491 1 Opera 1 Opera Browser 2023-12-10 2.6 LOW N/A
A race condition in Opera web browser 7.53 Build 3850 causes Opera to fill in the address bar before the page has been loaded, which allows remote attackers to spoof the URL in the address bar via the window.open and location.replace HTML parameters, which facilitates phishing attacks.
CVE-2005-0457 1 Opera 1 Opera Browser 2023-12-10 7.2 HIGH N/A
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.
CVE-2004-1491 4 Gentoo, Kde, Opera and 1 more 4 Linux, Kde, Opera Browser and 1 more 2023-12-10 5.0 MEDIUM N/A
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.
CVE-2004-1810 1 Opera 1 Opera Browser 2023-12-10 5.0 MEDIUM N/A
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.
CVE-2003-1396 1 Opera 1 Opera Browser 2023-12-10 6.8 MEDIUM N/A
Heap-based buffer overflow in Opera 6.05 through 7.10 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a filename with a long extension.
CVE-2004-0872 1 Opera 1 Opera Browser 2023-12-10 5.0 MEDIUM N/A
Opera does not prevent cookies that are sent over an insecure channel (HTTP) from also being sent over a secure channel (HTTPS/SSL) in the same domain, which could allow remote attackers to steal cookies and conduct unauthorized activities, aka "Cross Security Boundary Cookie Injection."
CVE-2003-1397 1 Opera 1 Opera Browser 2023-12-10 4.3 MEDIUM N/A
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.
CVE-2004-0717 3 Linux, Microsoft, Opera 3 Linux Kernel, Windows, Opera Browser 2023-12-10 7.5 HIGH N/A
Opera 7.51 for Windows and 7.50 for Linux does not properly prevent a frame in one domain from injecting content into a frame that belongs to another domain, which facilitates web site spoofing and other attacks, aka the frame injection vulnerability.
CVE-2004-0473 1 Opera 1 Opera Browser 2023-12-10 2.6 LOW N/A
Argument injection vulnerability in Opera before 7.50 does not properly filter "-" characters that begin a hostname in a telnet URI, which allows remote attackers to insert options to the resulting command line and overwrite arbitrary files via (1) the "-f" option on Windows XP or (2) the "-n" option on Linux.
CVE-2003-1388 1 Opera 1 Opera Browser 2023-12-10 9.3 HIGH N/A
Buffer overflow in Opera 7.02 Build 2668 allows remote attackers to crash Opera via a long HTTP request ending in a .ZIP extension.
CVE-2003-0593 1 Opera 1 Opera Browser 2023-12-10 7.5 HIGH N/A
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.
CVE-2004-1489 1 Opera 1 Opera Browser 2023-12-10 2.6 LOW N/A
Opera 7.54 and earlier does not properly limit an applet's access to internal Java packages from Sun, which allows remote attackers to gain sensitive information, such as user names and the installation directory.
CVE-2003-0870 1 Opera 1 Opera Browser 2023-12-10 7.5 HIGH N/A
Heap-based buffer overflow in Opera 7.11 and 7.20 allows remote attackers to execute arbitrary code via an HREF with a large number of escaped characters in the server name.

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.
