Overview
Affected versions of this package are vulnerable to Improper Validation of Array Index through the ExtractMysqlComment function in comments.go and the MySQL special-comment handling in token.go. An attacker can crash the parser by supplying a malformed MySQL version comment such as an empty /*!...*/ comment or one whose contents are only one to five decimal digits. When Parse, ParseStrictDDL, or ParseNext processes that input, ExtractMysqlComment uses the result of strings.IndexFunc as a slice boundary without checking for -1, which triggers a Go runtime panic. Applications that parse attacker-controlled SQL can terminate if that panic is not recovered, and repeated requests can sustain a denial of service.
