## Description

In PHP 7.x before 7.0.21 and 7.1.x before 7.1.7,
ext/intl/msgformat/msgformat\_parse.c does not restrict the locale length,
which allows remote attackers to cause a denial of service (stack-based
buffer overflow and application crash) or possibly have unspecified other
impact within International Components for Unicode (ICU) for C/C++ via a
long first argument to the msgfmt\_parse\_message function.
