This allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) or read information from other memory locatiohttps://patchthecve.com/cve/CVE-2018-12437.htmlhttps://patchthecve.com/cve/CVE-2018-12437.htmlWed, 17 Jun 2026 01:37:47 +0000MEDIUM 4.9: 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 host.https://patchthecve.com/cve/CVE-2016-6129.htmlhttps://patchthecve.com/cve/CVE-2016-6129.htmlWed, 17 Jun 2026 00:50:30 +0000HIGH 7.5: 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 leveraging a Bleichenhttps://patchthecve.com/cve/CVE-2005-1600.htmlhttps://patchthecve.com/cve/CVE-2005-1600.htmlTue, 16 Jun 2026 22:13:21 +0000HIGH 7.5: 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.
