CVE-2006-3331 1 Opera 1 Opera Browser 2025-04-03 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-2005-2407 1 Opera 1 Opera Browser 2025-04-03 5.1 MEDIUM N/A
A design error in Opera 8.01 and earlier allows user-assisted attackers to execute arbitrary code by overlaying a malicious new window above a file download dialog box, then tricking the user into double-clicking on the "Run" button, aka "link hijacking".
CVE-2004-0717 3 Linux, Microsoft, Opera 3 Linux Kernel, Windows, Opera Browser 2025-04-03 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-2005-0233 4 Mozilla, Omnigroup, Opera and 1 more 6 Camino, Firefox, Mozilla and 3 more 2025-04-03 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-2004-1201 1 Opera 1 Opera Browser 2025-04-03 5.0 MEDIUM N/A
Opera 7.54 allows remote attackers to cause a denial of service (application crash from memory exhaustion), as demonstrated using Javascript code that continuously creates nested arrays and then sorts the newly created arrays.
CVE-2004-1491 4 Gentoo, Kde, Opera and 1 more 4 Linux, Kde, Opera Browser and 1 more 2025-04-03 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-2004-0537 1 Opera 1 Opera Browser 2025-04-03 5.0 MEDIUM N/A
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 8.01, when the "Arial Unicode MS" font (ARIALUNI.TTF) is installed, does not properly handle extended ASCII characters in the file download dialog box, which allows remote attackers to spoof file extensions and possibly trick users into executing arbitrary code.
CVE-2005-1139 1 Opera 1 Opera Browser 2025-04-03 7.5 HIGH N/A
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.
CVE-2006-3198 1 Opera 1 Opera Browser 2025-04-03 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-2005-2406 1 Opera 1 Opera Browser 2025-04-03 4.3 MEDIUM N/A
Opera 8.01 allows remote attackers to conduct cross-site scripting (XSS) attacks or modify which files are uploaded by tricking a user into dragging an image that is a "javascript:" URI.
CVE-2004-1615 1 Opera 1 Opera Browser 2025-04-03 2.6 LOW N/A
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.
CVE-2004-1157 1 Opera 1 Opera Browser 2025-04-03 7.5 HIGH N/A
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.
CVE-2004-1489 1 Opera 1 Opera Browser 2025-04-03 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-2004-2570 1 Opera 1 Opera Browser 2025-04-03 5.0 MEDIUM N/A
Opera before 7.54 allows remote attackers to modify properties and methods of the location object and execute Javascript to read arbitrary files from the client's local filesystem or display a false URL to the user.
CVE-2005-3006 1 Opera 1 Opera Browser 2025-04-03 5.0 MEDIUM N/A
The mail client in Opera before 8.50 opens attached files from the user's cache directory without warning the user, which might allow remote attackers to inject arbitrary web script and spoof attachment filenames.
CVE-2005-0456 1 Opera 1 Opera Browser 2025-04-03 5.0 MEDIUM N/A
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.
CVE-2006-3945 2 Microsoft, Opera 2 Windows Xp, Opera Browser 2025-04-03 5.0 MEDIUM N/A
The CSS functionality in Opera 9 on Windows XP SP2 allows remote attackers to cause a denial of service (crash) by setting the background property of a DHTML element to a long http or https URL, which triggers memory corruption.
