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-2005-1669 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-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-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-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.
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-2004-2570 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-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-2004-1810 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-2004-1157 1 Opera 1 Opera Browser 2026-04-16 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-2004-0717 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.
CVE-2005-2309 1 Opera 1 Opera Browser 2026-04-16 N/A
Opera 8.01 allows remote attackers to cause a denial of service (CPU consumption) via a crafted JPEG image, as demonstrated using random.jpg.
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-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-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-2003-0870 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-2005-4718 1 Opera 1 Opera Browser 2026-04-16 N/A
Opera 8.02 and earlier allows remote attackers to cause a denial of service (client crash) via (1) a crafted HTML file with a "content: url(0);" style attribute, a "bodyA" tag, a long string, and a "u" tag with a long attribute, as demonstrated by opera.html; and (2) a BGSOUND element with a "margin:-99;" STYLE attribute.
CVE-2004-1490 1 Opera 1 Opera Browser 2026-04-16 N/A
Opera 7.54 and earlier allows remote attackers to spoof file types in the download dialog via dots and non-breaking spaces (ASCII character code 160) in the (1) Content-Disposition or (2) Content-Type headers.
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.
