NVD Description

Note: Versions mentioned in the description apply only to the upstream rh-php70-php-json package and not the rh-php70-php-json package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

ext/intl/msgformat/msgformat_format.c in PHP before 5.6.26 and 7.x before 7.0.11 does not properly restrict the locale length provided to the Locale class in the ICU library, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a MessageFormatter::formatMessage call with a long first argument.
