Bad validation logic in the Dart SDK versions prior to 2.12.3 allow an attacker to use an XSS attack via DOM clobbering. The validation logic in dart:html for creating DOM nodes from text did not sanitize properly when it came across template tags.

An issue was discovered in the http package through 0.12.2 for Dart. If the attacker controls the HTTP method and the app is using Request directly, it's possible to achieve CRLF injection in an HTTP request.

An improper HTML sanitization in Dart versions up to and including 2.7.1 and dev versions 2.8.0-dev.16.0, allows an attacker leveraging DOM Clobbering techniques to skip the sanitization and inject custom html/javascript (XSS). Mitigation: update your Dart SDK to 2.7.2, and 2.8.0-dev.17.0 for the dev version. If you cannot update, we recommend you review the way you use the affected APIs, and pay special attention to cases where user-provided data is used to populate DOM nodes. Consider using Element.innerText or Node.text to populate DOM elements.

NULL Pointer Dereference in PowerTCP WebServer for ActiveX 1.9.2 and earlier allows remote attackers to cause a denial of service (application crash) via a crafted HTTP request.

Stack consumption vulnerability in dartwebserver.dll 1.9 and earlier, as used in Dart PowerTCP WebServer for ActiveX and other products, allows remote attackers to cause a denial of service (daemon crash) via a long request.

Buffer overflow in the ActiveX control (DartFtp.dll) in Dart Communications PowerTCP FTP for ActiveX 2.0.2 0 allows remote attackers to execute arbitrary code via a long SecretKey property.

Buffer overflow in a certain ActiveX control in DartZipLite.dll 1.8.5.3 in Dart ZipLite Compression for ActiveX allows user-assisted remote attackers to execute arbitrary code via a long first argument to the QuickZip function, a related issue to CVE-2007-2856.

Buffer overflow in the Dart Communications PowerTCP ZIP Compression ActiveX control in DartZip.dll 1.8.5.3, when Internet Explorer 6 is used, allows user-assisted remote attackers to execute arbitrary code via a long first argument to the QuickZip function, a related issue to CVE-2007-2855.
