Red Hat3.3CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L

Trivy's own label is CRITICAL. Rated critical by NVD, Photon OS. Rated lower by Ubuntu (medium), Red Hat (low).

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.
