| CVE | Vendors | Products | Updated | CVSS v3.1 |
|---|---|---|---|---|
| CVE-2011-3389 | 9 Canonical, Debian, Google and 6 more | 21 Ubuntu Linux, Debian Linux, Chrome and 18 more | 2026-10-09 | N/A |
| The SSL protocol, as used in certain configurations in Microsoft Windows and Microsoft Internet Explorer, Mozilla Firefox, Google Chrome, Opera, and other products, encrypts data by using CBC mode with chained initialization vectors, which allows man-in-the-middle attackers to obtain plaintext HTTP headers via a blockwise chosen-boundary attack (BCBA) on an HTTPS session, in conjunction with JavaScript code that uses (1) the HTML5 WebSocket API, (2) the Java URLConnection API, or (3) the Silverlight WebClient API, aka a "BEAST" attack. | ||||
| CVE-2015-4000 | 13 Apple, Canonical, Debian and 10 more | 31 Iphone Os, Mac Os X, Safari and 28 more | 2026-05-27 | 3.7 Low |
| The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue. | ||||
| 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-2008-2715 | 1 Opera | 1 Opera Browser | 2026-04-23 | N/A |
| Unspecified vulnerability in Opera before 9.5 allows remote attackers to read cross-domain images via HTML CANVAS elements that use the images as patterns. | ||||
| 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-2008-1080 | 1 Opera | 1 Opera Browser | 2026-04-23 | N/A |
| Opera before 9.26 allows user-assisted remote attackers to read arbitrary files by tricking a user into typing the characters of the target filename into a file input. | ||||
| CVE-2008-1762 | 1 Opera | 1 Opera Browser | 2026-04-23 | 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-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-2007-0126 | 1 Opera | 1 Opera Browser | 2026-04-23 | N/A |
| Heap-based buffer overflow in Opera 9.02 allows remote attackers to execute arbitrary code via a JPEG file with an invalid number of index bytes in the Define Huffman Table (DHT) marker. | ||||
| CVE-2009-3013 | 1 Opera | 1 Opera Browser | 2026-04-23 | N/A |
| Opera 9.52 and earlier, and 10.00 Beta 3 Build 1699, does not properly block data: URIs in Location headers in HTTP responses, which allows remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to (1) injecting a Location header that contains JavaScript sequences in a data:text/html URI or (2) entering a data:text/html URI with JavaScript sequences when specifying the content of a Location header. NOTE: the JavaScript executes outside of the context of the HTTP site. | ||||
| CVE-2008-5680 | 1 Opera | 1 Opera Browser | 2026-04-23 | N/A |
| Multiple buffer overflows in Opera before 9.63 might allow (1) remote attackers to execute arbitrary code via a crafted text area, or allow (2) user-assisted remote attackers to execute arbitrary code via a long host name in a file: URL. NOTE: this might overlap CVE-2008-5178. | ||||
| CVE-2009-2059 | 1 Opera | 1 Opera Browser | 2026-04-23 | N/A |
| Opera, possibly before 9.25, uses the HTTP Host header to determine the context of a document provided in a (1) 4xx or (2) 5xx CONNECT response from a proxy server, which allows man-in-the-middle attackers to execute arbitrary web script by modifying this CONNECT response, aka an "SSL tampering" attack. | ||||
| CVE-2009-2063 | 1 Opera | 1 Opera Browser | 2026-04-23 | 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-2009-2067 | 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-2009-2070 | 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-2009-2540 | 1 Opera | 1 Opera Browser | 2026-04-23 | 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-2008-4197 | 5 Freebsd, Linux, Microsoft and 2 more | 5 Freebsd, Linux Kernel, Windows and 2 more | 2026-04-23 | 8.8 High |
| Opera before 9.52 on Windows, Linux, FreeBSD, and Solaris, when processing custom shortcut and menu commands, can produce argument strings that contain uninitialized memory, which might allow user-assisted remote attackers to execute arbitrary code or conduct other attacks via vectors related to activation of a shortcut. | ||||
| CVE-2008-7245 | 1 Opera | 1 Opera Browser | 2026-04-23 | N/A |
| Opera 9.52 and earlier allows remote attackers to cause a denial of service (unusable browser) by calling the window.print function in a loop, aka a "printing DoS attack," possibly a related issue to CVE-2009-0821. | ||||
| CVE-2008-4697 | 1 Opera | 1 Opera Browser | 2026-04-23 | N/A |
| The Fast Forward feature in Opera before 9.61, when a page is located in a frame, executes a javascript: URL in the context of the outermost page instead of the page that contains this URL, which allows remote attackers to conduct cross-site scripting (XSS) attacks. | ||||
| CVE-2009-3832 | 2 Microsoft, Opera | 2 Windows, Opera Browser | 2026-04-23 | N/A |
| Opera before 10.01 on Windows does not prevent use of Web fonts in rendering the product's own user interface, which allows remote attackers to spoof the address field via a crafted web site. | ||||
