Vulnerabilidades

Opera 7.x up to 7.54, and possibly other versions, allows remote attackers to spoof arbitrary web sites by injecting content from one window into a target window whose name is known but resides in a different domain, as demonstrated using a pop-up window on a trusted web site, aka the "window injection" vulnerability.

Opera 7.54 and earlier uses kfmclient exec to handle unknown MIME types, which allows remote attackers to execute arbitrary code via a shortcut or launcher that contains an Exec entry.

Format string vulnerability in the Lithtech engine, as used in multiple games, allows remote authenticated users to cause a denial of service (application crash) via format string specifiers in (1) a nickname or (2) a message.

Opera Browser 7.23, and other versions before 7.50, updates the address bar as soon as the user clicks a link, which allows remote attackers to redirect to other sites via the onUnload attribute.

Opera 7.54 and earlier does not properly limit an applet's access to internal Java packages from Sun, which allows remote attackers to gain sensitive information, such as user names and the installation directory.

The Javascript engine in Opera 7.23 allows remote attackers to cause a denial of service (crash) by creating a new Array object with a large size value, then writing into that array.

Opera 7.54 and earlier allows remote attackers to spoof file types in the download dialog via dots and non-breaking spaces (ASCII character code 160) in the (1) Content-Disposition or (2) Content-Type headers.

A race condition in Opera web browser 7.53 Build 3850 causes Opera to fill in the address bar before the page has been loaded, which allows remote attackers to spoof the URL in the address bar via the window.open and location.replace HTML parameters, which facilitates phishing attacks.

Opera before 7.54 allows remote attackers to modify properties and methods of the location object and execute Javascript to read arbitrary files from the client's local filesystem or display a false URL to the user.

Opera offers an Open button to verify that a user wishes to execute a downloaded file, which allows user-assisted remote attackers to construct a race condition that tricks a user into clicking Open via a request for a different mouse or keyboard action very shortly before the Open dialog appears. NOTE: this is a…

Opera allows remote attackers to cause a denial of service (invalid memory reference and application crash) via a web page or HTML email that contains a TBODY tag with a large COL SPAN value, as demonstrated by mangleme.

Opera does not prevent cookies that are sent over an insecure channel (HTTP) from also being sent over a secure channel (HTTPS/SSL) in the same domain, which could allow remote attackers to steal cookies and conduct unauthorized activities, aka "Cross Security Boundary Cookie Injection."

Engenio/LSI Logic storage controllers, as used in products such as Storagetek D280, and IBM DS4100 (formerly FastT 100) and Brocade SilkWorm Switches, allow remote attackers to cause a denial of service (freeze and possible data corruption) via crafted TCP packets.

Ground Control II: Operation Exodus 1.0.0.7 and earlier allows remote servers to cause a denial of service (client or server crash) via a large packet, which generates a "Message too long" socket error that is treated as a critical error.

Opera 7.50 y anteriores permite a sitios web remotos suministrar un "Icono de acceso directo" (favicon) que es más ancho de lo esperado, lo que podría permitir a los sitios web suplantar un dominio de confianza y facilitar ataques de phising usando un icono ancho y espacios extra.

Opera 7.51 para Windows y 7.50 para Linux no previene apropiadamente que un marco de un dominio inyecte contenido en un marco que pertenece a otro dominio, lo que facilita la suplantación de sitios web y otros ataques. También conocida como vulnerabilidad de inyección en marcos.

El navegador Web Opera no filtra adecuadamente caractéres "-" en el comienzo de un nombre de máquina en una URI telnet, lo que permite a atacantes remotos insertar opciones en la linea de comandos resultante y sobreescribir ficheros de su elección mediante la opción "-f" en Windows XP o "-n" en Linux.

Opera permite a atacantes remotos saltarse las restriciones de cookies pretendidas en una aplicación web mediante secuencias de atravesamiento de directorios "%2e%2e" (punto punto codificado) en una URL, lo que hace que Opera envíe la cookie fuera de los subconjuntos de URL especificados, por ejemplo a una aplicación…

Opera Web Browser 7.0 through 7.23 allows remote attackers to trick users into executing a malicious file by embedding a CLSID in the file name, which causes the malicious file to appear as a trusted file type, aka "File Download Extension Spoofing."

The PluginContext object of Opera 6.05 and 7.0 allows remote attackers to cause a denial of service (crash) via an HTTP request containing a long string that gets passed to the ShowDocument method.

Heap-based buffer overflow in Opera 6.05 through 7.10 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a filename with a long extension.

Buffer overflow in Opera 6.05 and 6.06, and possibly other versions, allows remote attackers to execute arbitrary code via a URL with a long username.

Cross-site scripting (XSS) vulnerability in Opera 6.0 through 7.0 with automatic redirection disabled allows remote attackers to inject arbitrary web script or HTML via the HTTP Location header.

Opera, probably before 7.50, sends Referer headers containing https:// URLs in requests for http:// URLs, which allows remote attackers to obtain potentially sensitive information by reading Referer log data.

Buffer overflow in Opera 7.02 Build 2668 allows remote attackers to crash Opera via a long HTTP request ending in a .ZIP extension.
