Regular Expression Denial Of Service (ReDoS)

get-func-name is vulnerable to Regular Expression Denial Of Service. The vulnerability is due to the getFuncName function in index.js not properly checking the functionSource size and length. which allows an attacker to trigger a DOS attack by using an input like '\t'.repeat(54773) + '\t/function/i', which exploits the regular expression’s weakness in functionNameMatch to create excessive backtracking.
