CVE-2008-4200 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera before 9.52 does not ensure that the address field of a news feed represents the feed's actual URL, which allows remote attackers to change this field to display the URL of a page containing web script controlled by the attacker.
CVE-2008-4293 2 Microsoft, Opera 2 Windows, Opera 2025-04-09 N/A
Unspecified vulnerability in Opera before 9.52 on Windows, when registered as a protocol handler, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unknown vectors in which Opera is launched by other applications.
CVE-2008-4696 1 Opera 1 Opera 2025-04-09 N/A
Cross-site scripting (XSS) vulnerability in Opera.dll in Opera before 9.61 allows remote attackers to inject arbitrary web script or HTML via the anchor identifier (aka the "optional fragment"), which is not properly escaped before storage in the History Search database (aka md.dat).
CVE-2008-4698 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera before 9.61 does not properly block scripts during preview of a news feed, which allows remote attackers to create arbitrary new feed subscriptions and read the contents of arbitrary feeds.
CVE-2009-2067 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera detects http content in https web pages only when the top-level frame uses https, which allows man-in-the-middle attackers to execute arbitrary web script, in an https site's context, by modifying an http page to include an https iframe that references a script file on an http site, related to "HTTP-Intended-but-HTTPS-Loadable (HPIHSL) pages."
CVE-2008-5681 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera before 9.63 does not block unspecified "scripted URLs" during the feed preview, which allows remote attackers to read existing subscriptions and force subscriptions to arbitrary feed URLs.
CVE-2008-5682 1 Opera 1 Opera Browser 2025-04-09 N/A
Cross-site scripting (XSS) vulnerability in Opera before 9.63 allows remote attackers to inject arbitrary web script or HTML via built-in XSLT templates.
CVE-2008-5683 1 Opera 1 Opera Browser 2025-04-09 N/A
Unspecified vulnerability in Opera before 9.63 allows remote attackers to "reveal random data" via unknown vectors.
CVE-2009-0914 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera before 9.64 allows remote attackers to execute arbitrary code via a crafted JPEG image that triggers memory corruption.
CVE-2009-0915 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera before 9.64 allows remote attackers to conduct cross-domain scripting attacks via unspecified vectors related to plug-ins.
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-2009-2068 1 Opera 1 Opera 2025-04-09 N/A
Google Chrome detects http content in https web pages only when the top-level frame uses https, which allows man-in-the-middle attackers to execute arbitrary web script, in an https site's context, by modifying an http page to include an https iframe that references a script file on an http site, related to "HTTP-Intended-but-HTTPS-Loadable (HPIHSL) pages."
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-2009-2540 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.
