Opera 9 drops DNS pins based on failed connections to irrelevant TCP ports, which makes it easier for remote attackers to conduct DNS rebinding attacks, as demonstrated by a port 81 URL in an IMG SRC, when the DNS pin had been established for a session on port 80.

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.

Opera before 9.25 allows remote attackers to conduct cross-domain scripting attacks via unknown vectors related to plug-ins.

Unspecified vulnerability in Opera before 9.25 allows remote attackers to execute arbitrary code via crafted TLS certificates.

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.

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.

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.

Opera before 9.26 allows remote attackers to misrepresent web page addresses using "certain characters" that "cause the page address text to be misplaced."

Unspecified vulnerability in Opera before 9.5 allows remote attackers to spoof the contents of trusted frames on the same parent page by modifying the location, which can facilitate phishing attacks.

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.

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.

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.

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.

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.

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.

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.

Adobe Macromedia Flash Player 7 and 9, when used with Opera before 9.20 or Konqueror before 20070613, allows remote attackers to obtain sensitive information (browser keystrokes), which are leaked to the Flash Player applet.

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.

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.

Opera 9.21 allows remote attackers to spoof the data: URI scheme in the address bar via a long URI with trailing whitespace, which prevents the beginning of the URI from being displayed.
