Justin B Rye has reported a weakness in polygen, which can be exploited by malicious, local users to manipulate certain information.
The weakness is due to polygen creating its output grammar object files with world-writable permissions, instead of using the umask settings. This can potentially be exploited by malicious users to delete or corrupt the contents of the generated files.
The weakness has been reported in version 1.0.6. Other versions may also be affected.
Solution: Remove write permissions from the files after they have been generated.
