 BadParser is a vulnerable parser designed to aid in the testing of fuzzers by simulating different kinds of memory corruption issues. Vulnerabilities are simulated by causing write-access violations at specific addresses, which serve as unique identifiers for the different issues.
 
-Currently BadParser only supports JSON input files, but other file formats are planned.
