Algorithmic complexity vulnerability in Opera 9.50 beta and 9.x before 9.25 allows remote attackers to cause a denial of service (CPU consumption) via a crafted bitmap (BMP) file that triggers a large number of calculations and checks.
CVE-2008-3078 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera before 9.51 does not properly manage memory within functions supporting the CANVAS element, which allows remote attackers to read uninitialized memory contents by using JavaScript to read a canvas image.
CVE-2007-2809 1 Opera 1 Opera Browser 2026-04-23 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-2006-6955 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera allows remote attackers to cause a denial of service (application crash) via a web page that contains a large number of nested marquee tags, a related issue to CVE-2006-2723.
CVE-2006-6970 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera 9.10 Final allows remote attackers to bypass the Fraud Protection mechanism by adding certain characters to the end of a domain name, as demonstrated by the "." and "/" characters, which is not caught by the blacklist filter.

CVE-2007-0127 1 Opera 1 Opera Browser 2026-04-23 N/A
The Javascript SVG support in Opera before 9.10 does not properly validate object types in a createSVGTransformFromMatrix request, which allows remote attackers to execute arbitrary code via JavaScript code that uses an invalid object in this request that causes a controlled pointer to be referenced during the virtual function call.
CVE-2007-1737 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera 9.10 does not check URLs embedded in (1) object or (2) iframe HTML tags against the phishing site blacklist, which allows remote attackers to bypass phishing protection.
CVE-2009-2351 1 Opera 1 Opera Browser 2026-04-23 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-2009-2067 1 Opera 1 Opera Browser 2026-04-23 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-2009-2068 1 Opera 1 Opera 2026-04-23 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 2026-04-23 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-2008-4199 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera before 9.52 does not prevent use of links from web pages to feed source files on the local disk, which might allow remote attackers to determine the validity of local filenames via vectors involving "detection of JavaScript events and appropriate manipulation."
CVE-2008-4200 1 Opera 1 Opera Browser 2026-04-23 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.
