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.

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2025:0362 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2019-17362:
    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.
