Out-of-bounds read vulnerability in PHP's locale_accept_from_http function

CVE-2016-6294 · HIGH Severity

AV:N/AC:L/AU:N/C:P/I:P/A:P

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.
