| CVE-2025-40912 | Cri | 0.64 | 9.8 | 0.00 | Jun 11, 2025 | CryptX for Perl before version 0.065 contains a dependency that may be susceptible to malformed unicode. CryptX embeds the tomcrypt library. The versions of that library in CryptX before 0.065 may be susceptible to CVE-2019-17362. | ||
| CVE-2019-17362 | Cri | 0.52 | 9.1 | 0.03 | Oct 9, 2019 | 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… | ||
| CVE-2016-6129 | Hig | 0.49 | 7.5 | 0.01 | Feb 13, 2017 | The rsa_verify_hash_ex function in rsa_verify_hash.c in LibTomCrypt, as used in OP-TEE before 2.2.0, does not validate that the message length is equal to the ASN.1 encoded data length, which makes it easier for remote attackers to forge RSA signatures or public certificates by… | ||
| CVE-2018-12437 | Med | 0.32 | 4.9 | 0.01 | Jun 15, 2018 | LibTomCrypt through 1.18.1 allows a memory-cache side-channel attack on ECDSA signatures, aka the Return Of the Hidden Number Problem or ROHNP. To discover an ECDSA key, the attacker needs access to either the local machine or a different virtual machine on the same physical… | ||
| CVE-2005-1600 | 0.00 | — | 0.01 | May 16, 2005 | A "mathematical flaw" in the implementation of the El Gamal signature algorithm for LibTomCrypt 1.0 to 1.0.2 allows attackers to generate valid signatures without having the private key. |
