CVE-2016-6293
CriticalSummary
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.
Risk Assessment
The risk is that a remote attacker can crash an application using ICU by sending a crafted HTTP request with a long Accept-Language header, potentially leading to denial of service.
Recommendation
It is recommended to upgrade ICU library to a version later than 57.1, where this vulnerability is fixed, or apply a security patch from the software vendor.
