|---|---|---|---|---|---|
| CVE-2007-5274 | 3 Mozilla, Opera, Sun | 5 Firefox, Opera Browser, Jdk and 2 more | 2026-04-23 | 2.6 LOW | N/A |
| Sun Java Runtime Environment (JRE) in JDK and JRE 6 Update 2 and earlier, JDK and JRE 5.0 Update 12 and earlier, SDK and JRE 1.4.2_15 and earlier, and SDK and JRE 1.3.1_20 and earlier, when Firefox or Opera is used, allows remote attackers to violate the security model for JavaScript outbound connections via a multi-pin DNS rebinding attack dependent on the LiveConnect API, in which JavaScript download relies on DNS resolution by the browser, but JavaScript socket operations rely on separate DNS resolution by a Java Virtual Machine (JVM), a different issue than CVE-2007-5273. NOTE: this is similar to CVE-2007-5232. | |||||
| CVE-2006-6955 | 1 Opera | 1 Opera Browser | 2026-04-23 | 4.3 MEDIUM | 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-2009-4071 | 1 Opera | 1 Opera Browser | 2026-04-23 | 5.8 MEDIUM | N/A |
| Opera before 10.10, when exception stacktraces are enabled, places scripting error messages from a web site into variables that can be read by a different web site, which allows remote attackers to obtain sensitive information or conduct cross-site scripting (XSS) attacks via unspecified vectors. | |||||
| CVE-2009-2577 | 1 Opera | 1 Opera Browser | 2026-04-23 | 5.0 MEDIUM | 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-2009-2059 | 1 Opera | 1 Opera Browser | 2026-04-23 | 6.8 MEDIUM | 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-2008-4292 | 1 Opera | 1 Opera Browser | 2026-04-23 | 10.0 HIGH | N/A |
| Opera before 9.52 does not check the CRL override upon encountering a certificate that lacks a CRL, which has unknown impact and attack vectors. NOTE: it is not clear whether this is a vulnerability, but the vendor included it in a security section of the advisory. | |||||
| CVE-2007-0126 | 1 Opera | 1 Opera Browser | 2026-04-23 | 9.3 HIGH | 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-2007-1563 | 1 Opera | 1 Opera Browser | 2026-04-23 | 6.8 MEDIUM | N/A |
| The FTP protocol implementation in Opera 9.10 allows remote attackers to allows remote servers to force the client to connect to other servers, perform a proxied port scan, or obtain sensitive information by specifying an alternate server address in an FTP PASV response. | |||||
| CVE-2006-4819 | 1 Opera | 1 Opera Browser | 2026-04-23 | 5.1 MEDIUM | N/A |
| Heap-based buffer overflow in Opera 9.0 and 9.01 allows remote attackers to execute arbitrary code via a long URL in a tag (long link address). | |||||
| CVE-2009-3013 | 1 Opera | 1 Opera Browser | 2026-04-23 | 4.3 MEDIUM | 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-2009-2067 | 1 Opera | 1 Opera Browser | 2026-04-23 | 6.8 MEDIUM | 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-2007-6524 | 1 Opera | 1 Opera Browser | 2026-04-23 | 7.8 HIGH | N/A |
| Opera before 9.25 allows remote attackers to obtain potentially sensitive memory contents via a crafted bitmap (BMP) file, as demonstrated using a CANVAS element and JavaScript in an HTML document for copying these contents from 9.50 beta, a related issue to CVE-2008-0420. | |||||
| CVE-2008-1082 | 1 Opera | 1 Opera Browser | 2026-04-23 | 4.3 MEDIUM | N/A |
| Opera before 9.26 allows remote attackers to "bypass sanitization filters" and conduct cross-site scripting (XSS) attacks via crafted attribute values in an XML document, which are not properly handled during DOM presentation. | |||||
| CVE-2008-5681 | 1 Opera | 1 Opera Browser | 2026-04-23 | 4.3 MEDIUM | 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-2008-4200 | 1 Opera | 1 Opera Browser | 2026-04-23 | 6.4 MEDIUM | 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-2008-4698 | 1 Opera | 1 Opera Browser | 2026-04-23 | 5.8 MEDIUM | 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-2009-3831 | 2 Microsoft, Opera | 2 Windows, Opera Browser | 2026-04-23 | 9.3 HIGH | 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. | |||||

| 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-2008-1080 | 1 Opera | 1 Opera Browser | 2026-04-23 | 6.8 MEDIUM | N/A |
