PHP Out-of-bounds Read Vulnerability - CVE-2016-6294
The locale_accept_from_http function in ext/intl/locale/locale_methods.c in PHP before 5.5.38 5.6.x before 5.6.24 and 7.x before 7.0.9 does not properly restrict calls to the ICU uloc_acceptLanguageFromHTTP function which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a call with a long argument.
