CVE-2019-17362: libtomcrypt: out-of-bounds read in the der_decode_utf8_string function in der_decode_utf8_string.c

Severity: Critical

CVSS Score: 9.1

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.
