CVE-2016-6293
9.8
CRITICAL · CVSS 3.0 · EPSS 5% (pctl 92)
In your normal cycle
Critical by CVSS (9.8), but no sign of active exploitation.
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.
