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.
| Software | From | Fixed in |
|---|---|---|
| libtom / libtomcrypt | - | 1.18.2.x |
| debian / debian_linux | 8.0 | 8.0.x |
