libtomcrypt: CVE-2019-17362

Severity: Medium
Published: Oct 9, 2019, 12:00:00 AM UTC
Source: [NVD] · [CVE record]
EPSS: 3.11% · Oct 22, 2026

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.
