CVE-2016-6293

CRITICAL

International Components for Unicode < 57.1 - Out-of-Bounds Read via uloc_acceptLanguageFromHTTP

Title source: llm
STIX 2.1

Description

The uloc_acceptLanguageFromHTTP function in common/uloc.cpp in International Components for Unicode (ICU) through 57.1 for C/C++ does not ensure that there is a '\0' character at the end of a certain temporary array, 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 httpAcceptLanguage argument.
