Cross-site scripting (XSS) vulnerability in the MozSearch plugin implementation in Mozilla Firefox before 3.0.9 allows user-assisted remote attackers to inject arbitrary web script or HTML via a javascript: URI in the SearchForm element.
Mozilla Firefox before 3.0.9 and SeaMonkey before 1.1.17 allow user-assisted remote attackers to obtain sensitive information via a web page with an embedded frame, which causes POST data from an outer page to be sent to the inner frame's URL during a SAVEMODE_FILEONLY save of the inner frame.
Mozilla Firefox before 3.0.9 and SeaMonkey 1.1.17 do not block javascript: URIs in Refresh headers in HTTP responses, which allows remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to (1) injecting a Refresh header or (2) specifying the content of a Refresh header. NOTE: it was later reported that Firefox 3.6 a1 pre and Mozilla 1.7.x and earlier are also affected.
Mozilla Firefox 3.0.8 and earlier 3.0.x versions allows remote attackers to cause a denial of service (memory corruption) via an XML document composed of a long series of start-tags with no corresponding end-tags. NOTE: it was later reported that 3.0.10 and earlier are also affected.
The txMozillaXSLTProcessor::TransformToDoc function in Mozilla Firefox before 3.0.8 and SeaMonkey before 1.1.16 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via an XML file with a crafted XSLT transform.
Mozilla Firefox 3.0.7 on Windows 7 allows remote attackers to execute arbitrary code via unknown vectors related to the _moveToEdgeShift XUL tree method, which triggers garbage collection on objects that are still in use, as demonstrated by Nils during a PWN2OWN competition at CanSecWest 2009.
Interaction error in xdg-open allows remote attackers to execute arbitrary code by sending a file with a dangerous MIME type but using a safe type that Firefox sends to xdg-open, which causes xdg-open to process the dangerous file type through automatic type detection, as demonstrated by overwriting the .desktop file.
The skype_tool.copy_num method in the Skype extension BETA 2.2.0.95 for Firefox allows remote attackers to write arbitrary data to the clipboard via a string argument.
Adobe Flash Player 9.0.124.0 and earlier, when a Mozilla browser is used, does not properly interpret jar: URLs, which allows attackers to obtain sensitive information via unknown vectors.
The XPConnect component in Mozilla Firefox before 2.0.0.17 allows remote attackers to "pollute XPCNativeWrappers" and execute arbitrary code with chrome privileges via vectors related to a SCRIPT element.
