Some vulnerabilities have been reported in Foxit Reader, which can be exploited by malicious people to compromise a user's system.
1) An error exists when processing JBIG2 symbol dictionary segments. This can be exploited to dereference uninitialised memory via a specially crafted PDF file.
2) A boundary error exists in the processing of actions defined in PDF files. This can be exploited to cause a stack-based buffer overflow when an action having an overly long filename argument is triggered.
Successful exploitation of the vulnerabilities may allow execution of arbitrary code.
3) Actions defined in PDF files are executed without asking for confirmation when a trigger condition is satisfied. This can be exploited to execute arbitrary local programs with arbitrary parameters.
Successful exploitation of this vulnerability allows execution of arbitrary commands.
Vulnerabilities #1 and #3 are confirmed in version 3.0.2009.1301 and reported in versions 2.3 and 3.0. Vulnerability #2 is reported in version 3.0.
Solution: Update to version 3.0 Build 1506 or version 2.3 Build 3902.
