Foxit Reader Multiple Vulnerabilities

Multiple vulnerabilities have been identified in Foxit Reader, which could be exploited by attackers to compromise a vulnerable system.

1. A stack overflow error when processing a PDF containing an action (e.g. Open/Execute a file) with an overly long filename argument, which could be exploited to crash an affected application or execute arbitrary code.

2. An error when processing JBIG2 symbol dictionary segments, which could be exploited to dereference uninitialised memory via a specially crafted PDF file.

3. An error when processing an Open/Execute a file action defined in a PDF file, which could cause the application to open/execute the file defined by the creator of the PDF file without asking the user for confirmation when the trigger condition is satisfied.
