CVE-2008-1762 1 Opera 1 Opera Browser 2025-04-09 9.3 HIGH N/A
Opera before 9.27 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted scaled image pattern in an HTML CANVAS element, which triggers memory corruption.
CVE-2007-3142 1 Opera 1 Opera Browser 2025-04-09 5.8 MEDIUM N/A
Visual truncation vulnerability in Opera 9.21 allows remote attackers to spoof the address bar and possibly conduct phishing attacks via a long hostname, which is truncated after 34 characters, as demonstrated by a phishing attack using HTTP Basic Authentication.
CVE-2007-4367 1 Opera 1 Opera Browser 2025-04-09 9.3 HIGH N/A
Opera before 9.23 allows remote attackers to execute arbitrary code via crafted Javascript that triggers a "virtual function call on an invalid pointer."
CVE-2008-5428 2 Microsoft, Opera 2 Windows Xp, Opera 2025-04-09 4.3 MEDIUM N/A
Opera 9.51 on Windows XP does not properly handle (1) multipart/mixed e-mail messages with many MIME parts and possibly (2) e-mail messages with many "Content-type: message/rfc822;" headers, which allows remote attackers to cause a denial of service (stack consumption or other resource consumption) via a large e-mail message, a related issue to CVE-2006-1173.
CVE-2007-2809 1 Opera 1 Opera Browser 2025-04-09 9.3 HIGH N/A
Buffer overflow in the transfer manager in Opera before 9.21 for Windows allows user-assisted remote attackers to execute arbitrary code via a crafted torrent file. NOTE: due to the lack of details, it is not clear if this is the same issue as CVE-2007-2274.
CVE-2008-4694 1 Opera 1 Opera Browser 2025-04-09 9.3 HIGH N/A
Unspecified vulnerability in Opera before 9.60 allows remote attackers to cause a denial of service (application crash) or execute arbitrary code via a redirect that specifies a crafted URL.
CVE-2007-4944 1 Opera 1 Opera Browser 2025-04-09 5.0 MEDIUM N/A
The canvas.createPattern function in Opera 9.x before 9.22 for Linux, FreeBSD, and Solaris does not clear memory before using it to process a new pattern, which allows remote attackers to obtain sensitive information (memory contents) via JavaScript.
CVE-2008-4725 1 Opera 1 Opera Browser 2025-04-09 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in Opera.dll in Opera 9.52 allows remote attackers to inject arbitrary web script or HTML via the query string, which is not properly escaped before storage in the History Search database (aka md.dat), a different vector than CVE-2008-4696. NOTE: some of these issues were addressed before 9.60.
CVE-2008-3079 2 Microsoft, Opera 2 Windows, Opera 2025-04-09 10.0 HIGH N/A
Unspecified vulnerability in Opera before 9.51 on Windows allows attackers to execute arbitrary code via unknown vectors.
CVE-2009-3048 4 Conectiva, Freebsd, Opera and 1 more 4 Linux, Freebsd, Opera Browser and 1 more 2025-04-09 4.3 MEDIUM N/A
Opera before 10.00 on Linux, Solaris, and FreeBSD does not properly implement the "INPUT TYPE=file" functionality, which allows remote attackers to trick a user into uploading an unintended file via vectors involving a "dropped file."
CVE-2005-0235 1 Opera 1 Opera Browser 2025-04-03 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-2003-1396 1 Opera 1 Opera Browser 2025-04-03 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-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-2003-1387 1 Opera 1 Opera Browser 2025-04-03 7.5 HIGH 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-2004-2659 2 Mozilla, Opera 2 Mozilla, Opera Browser 2025-04-03 4.0 MEDIUM 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-2005-3750 1 Opera 1 Opera Browser 2025-04-03 7.5 HIGH N/A
Opera before 8.51 on Linux and Unix systems allows remote attackers to execute arbitrary code via shell metacharacters (backticks) in a URL that another product provides in a command line argument when launching Opera.
CVE-2004-2491 1 Opera 1 Opera Browser 2025-04-03 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-2005-1139 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.

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-2005-1475 1 Opera 1 Opera Browser 2025-04-03 7.5 HIGH 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.
