Trivy's own label is CRITICAL. Rated critical by NVD, Azure Linux, CBL-Mariner. Rated lower by Red Hat (medium), Ubuntu (medium).

Description

In LibTomCrypt through 1.18.2, the der_decode_utf8_string function (in der_decode_utf8_string.c) does not properly detect certain invalid UTF-8 sequences. This allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) or read information from other memory locations via carefully crafted DER-encoded data.
