CVE-2008-4697 1 Opera 1 Opera Browser 2024-02-28 4.3 MEDIUM 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-2009-3831 2 Microsoft, Opera 2 Windows, Opera Browser 2024-02-28 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.
CVE-2008-4199 1 Opera 1 Opera Browser 2024-02-28 5.0 MEDIUM 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-2008-1081 1 Opera 1 Opera Browser 2024-02-28 6.8 MEDIUM N/A
Opera before 9.26 allows user-assisted remote attackers to execute arbitrary script via images that contain custom comments, which are treated as script when the user displays the image properties.
CVE-2007-1377 4 Adobe, Mozilla, Netscape and 1 more 4 Acrobat Reader, Firefox, Navigator and 1 more 2024-02-28 5.0 MEDIUM N/A
AcroPDF.DLL in Adobe Reader 8.0, when accessed from Mozilla Firefox, Netscape, or Opera, allows remote attackers to cause a denial of service (unspecified resource consumption) via a .pdf URL with an anchor identifier that begins with search= followed by many %n sequences, a different vulnerability than CVE-2006-6027 and CVE-2006-6236.
CVE-2007-5476 3 Adobe, Apple, Opera 3 Flash Player, Mac Os X, Opera Browser 2024-02-28 10.0 HIGH N/A
Unspecified vulnerability in Adobe Flash Player 9.0.47.0 and earlier, when running on Opera before 9.24 on Mac OS X, has unknown "Highly Severe" impact and unknown attack vectors.
CVE-2007-6522 1 Opera 1 Opera Browser 2024-02-28 4.3 MEDIUM N/A
The rich text editing functionality in Opera before 9.25 allows remote attackers to conduct cross-domain scripting attacks by using designMode to modify contents of pages in other domains.
CVE-2007-3142 1 Opera 1 Opera Browser 2024-02-28 5.8 MEDIUM N/A
Visual truncation vulnerability in Opera 9.21 allows remote attackers to spoof the address bar and possibly conduct phishing attacks via a long hostname, which is truncated after 34 characters, as demonstrated by a phishing attack using HTTP Basic Authentication.
CVE-2007-3929 1 Opera 1 Opera Browser 2024-02-28 9.3 HIGH N/A
Use-after-free vulnerability in the BitTorrent support in Opera before 9.22 allows user-assisted remote attackers to execute arbitrary code via a crafted header in a torrent file, which leaves a dangling pointer to an invalid object.
CVE-2007-5540 1 Opera 1 Opera Browser 2024-02-28 7.5 HIGH N/A
Unspecified vulnerability in Opera before 9.24 allows remote attackers to overwrite functions on pages from other domains and bypass the same-origin policy via unknown vectors.
CVE-2008-1080 1 Opera 1 Opera Browser 2024-02-28 6.8 MEDIUM 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-2007-2274 1 Opera 1 Opera Browser 2024-02-28 7.8 HIGH N/A
The BitTorrent implementation in Opera 9.2 allows remote attackers to cause a denial of service (CPU consumption and application crash) via a malformed torrent file. NOTE: the original disclosure refers to this as a memory leak, but it is not certain.
CVE-2007-0802 2 Mozilla, Opera 2 Firefox, Opera Browser 2024-02-28 6.4 MEDIUM N/A
Mozilla Firefox 2.0.0.1 allows remote attackers to bypass the Phishing Protection mechanism by adding certain characters to the end of the domain name, as demonstrated by the "." and "/" characters, which is not caught by the Phishing List blacklist filter.
CVE-2007-6524 1 Opera 1 Opera Browser 2024-02-28 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-2007-1115 1 Opera 1 Opera Browser 2024-02-28 4.3 MEDIUM N/A
The child frames in Opera 9 before 9.20 inherit the default charset from the parent window when a charset is not specified in an HTTP Content-Type header or META tag, which allows remote attackers to conduct cross-site scripting (XSS) attacks, as demonstrated using the UTF-7 character set.
CVE-2007-6523 1 Opera 1 Opera Browser 2024-02-28 7.8 HIGH N/A
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-2007-5274 3 Mozilla, Opera, Sun 5 Firefox, Opera Browser, Jdk and 2 more 2024-02-28 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-2007-6521 1 Opera 1 Opera Browser 2024-02-28 10.0 HIGH N/A
