CVE-2019-17362
9.1
CRITICAL · CVSS 3.1 · EPSS 3.1% (pctl 87)
In your normal cycle
Critical by CVSS (9.1), but no sign of active exploitation.
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.
