CVE-2009-1234 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera 9.64 allows remote attackers to cause a denial of service (application crash) via an XML document containing a long series of start-tags with no corresponding end-tags. NOTE: it was later reported that 9.52 is also affected.
CVE-2009-2063 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera, possibly before 9.25, processes a 3xx HTTP CONNECT response before a successful SSL handshake, which allows man-in-the-middle attackers to execute arbitrary web script, in an https site's context, by modifying this CONNECT response to specify a 302 redirect to an arbitrary https web site.
CVE-2009-2070 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera displays a cached certificate for a (1) 4xx or (2) 5xx CONNECT response page returned by a proxy server, which allows man-in-the-middle attackers to spoof an arbitrary https site by letting a browser obtain a valid certificate from this site during one request, and then sending the browser a crafted 502 response page upon a subsequent request.
CVE-2009-2351 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera 9.52 and earlier does not block javascript: URIs in Refresh headers in HTTP responses, which allows remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to (1) injecting a Refresh header or (2) specifying the content of a Refresh header, a related issue to CVE-2009-1312. NOTE: it was later reported that 10.00 Beta 3 Build 1699 is also affected.
CVE-2009-2540 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera, possibly 9.64 and earlier, allows remote attackers to cause a denial of service (memory consumption) via a large integer value for the length property of a Select object, a related issue to CVE-2009-1692.
CVE-2009-2577 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera 9.52 and earlier allows remote attackers to cause a denial of service (CPU and memory consumption, and application hang) via a long Unicode string argument to the write method, a related issue to CVE-2009-2479.
CVE-2009-3045 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera before 10.00 trusts root X.509 certificates signed with the MD2 algorithm, which makes it easier for man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted server certificate.
CVE-2009-3047 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera before 10.00, when a collapsed address bar is used, does not properly update the domain name from the previously visited site to the currently visited site, which might allow remote attackers to spoof URLs.
CVE-2009-3049 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera before 10.00 does not properly display all characters in Internationalized Domain Names (IDN) in the address bar, which allows remote attackers to spoof URLs and conduct phishing attacks, related to Unicode and Punycode.
CVE-2009-3265 1 Opera 1 Opera Browser 2025-04-09 N/A
Cross-site scripting (XSS) vulnerability in Opera 9 and 10 allows remote attackers to inject arbitrary web script or HTML via a (1) RSS or (2) Atom feed, related to the rendering of the application/rss+xml content type as "scripted content." NOTE: the vendor reportedly considers this behavior a "design feature," not a vulnerability.
CVE-2009-3831 2 Microsoft, Opera 2 Windows, Opera Browser 2025-04-09 N/A
Opera before 10.01 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted domain name.
CVE-2009-4072 1 Opera 1 Opera Browser 2025-04-09 N/A
Unspecified vulnerability in Opera before 10.10 has unknown impact and attack vectors, related to a "moderately severe issue."
CVE-2004-2659 2 Mozilla, Opera 2 Mozilla, Opera Browser 2025-04-03 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-2003-1388 1 Opera 1 Opera Browser 2025-04-03 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-2004-0537 1 Opera 1 Opera Browser 2025-04-03 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-2004-1201 1 Opera 1 Opera Browser 2025-04-03 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-2004-1489 1 Opera 1 Opera Browser 2025-04-03 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-2004-1490 1 Opera 1 Opera Browser 2025-04-03 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-2004-1491 4 Gentoo, Kde, Opera and 1 more 4 Linux, Kde, Opera Browser and 1 more 2025-04-03 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-2004-1615 1 Opera 1 Opera Browser 2025-04-03 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.
