CVE-2003-1387 1 Opera 1 Opera Browser 2026-04-16 N/A
Buffer overflow in Opera 6.05 and 6.06, and possibly other versions, allows remote attackers to execute arbitrary code via a URL with a long username.
CVE-2004-1615 1 Opera 1 Opera Browser 2026-04-16 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-2004-0473 1 Opera 1 Opera Browser 2026-04-16 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-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-2005-0238 4 Gnome, Mozilla, Omnigroup and 1 more 5 Epiphany, Camino, Mozilla and 2 more 2026-04-16 N/A
The International Domain Name (IDN) support in Epiphany 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-2005-1475 1 Opera 1 Opera Browser 2026-04-16 N/A
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.
CVE-2003-0593 1 Opera 1 Opera Browser 2026-04-16 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-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-2003-1561 1 Opera 1 Opera 2026-04-16 N/A
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.
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-2004-2659 2 Mozilla, Opera 2 Mozilla, Opera Browser 2026-04-16 N/A
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.
CVE-2004-2260 1 Opera 1 Opera Browser 2026-04-16 N/A
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.
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-2004-0872 1 Opera 1 Opera Browser 2026-04-16 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-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-2005-2405 1 Opera 1 Opera Browser 2026-04-16 N/A
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-2003-1397 1 Opera 1 Opera Browser 2026-04-16 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-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-2005-0233 5 Mozilla, Omnigroup, Opera and 2 more 7 Camino, Firefox, Mozilla and 4 more 2026-04-16 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.
