Opera Software : Security Vulnerabilities, CVEs, Published In 2002 CVSS score >= 1

Opera 6.0.3, when using Squid 2.4 for HTTPS proxying, does not properly handle when accepting a non-global certificate authority (CA) certificate from a site and establishing a subsequent HTTPS connection, which allows remote attackers to cause a denial of service (crash).

Cross-site scripting (XSS) vulnerability in the FTP view feature in Opera 6.0 and 6.01 through 6.04 allows remote attackers to inject arbitrary web script or HTML via the title tag of an FTP URL.

Buffer overflow in Opera 6.01 allows remote attackers to cause a denial of service (crash) via an IMG tag with large width and height attributes.

Opera 6.0.1 allows remote attackers to upload arbitrary file contents when users press a key corresponding to the JavaScript (1) event.ctrlKey or (2) event.shiftKey onkeydown event contained in a webpage.

Microsoft Internet Explorer 6.0 and possibly others allows remote attackers to upload arbitrary file contents when users press a key corresponding to the JavaScript (1) event.ctrlKey or (2) event.shiftKey onkeydown event contained in a webpage. NOTE: it was reported that the vendor has disputed the severity of this issue.

Netscape 6.2.3 and earlier, and Mozilla 1.0.1, allow remote attackers to corrupt heap memory and execute arbitrary code via a GIF image with a zero width.

Opera 6.0.1 and 6.0.2 allows a remote web site to upload arbitrary files from the client system, without prompting the client, via an input type=file tag whose value contains a newline.

Opera 6.01, 6.0, and 5.12 allows remote attackers to execute arbitrary JavaScript in the security context of other sites by setting the location of a frame or iframe to a Javascript: URL.

Opera, when configured with the "Determine action by MIME type" option disabled, interprets an object as an HTML document even when its MIME Content-Type is text/plain, which could allow remote attackers to execute arbitrary script in documents that the user does not expect, possibly through web applications that use a text/plain type to prevent cross-site scripting attacks.

Cross-site scripting vulnerability in Opera 6.0 and earlier allows remote attackers to execute arbitrary script via an Extended HTML Form, whose output from the remote server is not properly cleansed.
