CVE-2019-17362 (opens in a new tab)Amendment
The Debian security team deemed this advisory irrelevant for Debian:12.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libcryptx-perl package and not the libcryptx-perl package as distributed by Debian.
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.
