Description
Foxit Reader versions through 5.4.5.0114, including the bundled Foxit Reader Plugin 2.2.1.530, contains a stack-based buffer overflow vulnerability in the npFoxitReaderPlugin.dll module. When a PDF file is loaded from a remote host, an overly long query string in the URL can overflow a buffer, allowing remote attackers to execute arbitrary code.
