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-2004-2570 1 Opera 1 Opera Browser 2026-04-16 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-2006-3945 2 Microsoft, Opera 2 Windows Xp, Opera Browser 2026-04-16 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.
CVE-2003-0870 1 Opera 1 Opera Browser 2026-04-16 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.
CVE-2004-2083 1 Opera 1 Opera Browser 2026-04-16 N/A
Opera Web Browser 7.0 through 7.23 allows remote attackers to trick users into executing a malicious file by embedding a CLSID in the file name, which causes the malicious file to appear as a trusted file type, aka "File Download Extension Spoofing."
CVE-2004-0537 1 Opera 1 Opera Browser 2026-04-16 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.
CVE-2006-3331 1 Opera 1 Opera Browser 2026-04-16 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-2005-3006 1 Opera 1 Opera Browser 2026-04-16 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-2005-3007 1 Opera 1 Opera Browser 2026-04-16 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-2004-2491 1 Opera 1 Opera Browser 2026-04-16 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-2004-1810 1 Opera 1 Opera Browser 2026-04-16 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-2006-1834 1 Opera 1 Opera Browser 2026-04-16 N/A
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.
CVE-2003-1388 1 Opera 1 Opera Browser 2026-04-16 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-2003-1396 1 Opera 1 Opera Browser 2026-04-16 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-2005-1669 1 Opera 1 Opera Browser 2026-04-16 N/A
Cross-site scripting (XSS) vulnerability in Opera 8.0 Final Build 1095 allows remote attackers to inject arbitrary web script or HTML via "javascript:" URLs when a new window or frame is opened, which allows remote attackers to bypass access restrictions and perform unauthorized actions on other domains.
CVE-2004-0717 3 Linux, Microsoft, Opera 3 Linux Kernel, Windows, Opera Browser 2026-04-16 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.
