Overview

Affected versions of this package are vulnerable to Denial of Service (DoS). Perl-Compatible Regular Expression (PCRE) library before 7.3 reads past the end of the string when searching for unmatched brackets and parentheses, which allows context-dependent attackers to cause a denial of service (crash), possibly involving forward references.
