Add an init guard to prevent authenticode parser reinitialize #1923

Closed kylereedmsft closed 1 year ago

kylereedmsft commented 1 year ago

We use libyara in a process that can initialize/finialize and then re-initialize yara. After #1623 was merged, calling initialize the second time caused failures.

This change adds a static guard around the initialize_authenticode_parser call in pe module's initialize so that it won't be initialized more than once per process.
