Title
Cryptlib: rsa key exchange ciphersuites in tls vulnerable to marvin attack
Summary
A security vulnerability has been identified in the cryptlib cryptographic library when cryptlib is compiled with the support for RSA key exchange ciphersuites in TLS (by setting the USE_RSA_SUITES define), it will be vulnerable to the timing variant of the Bleichenbacher attack. An attacker that is able to perform a large number of connections to the server will be able to decrypt RSA ciphertexts or forge signatures using server's certificate.
Severity ?
5.9 (Medium)

CVE-2018-12433 (GCVE-0-2018-12433)
Vulnerability from cvelistv5 – Published: 2018-06-15 02:00 – Updated: 2024-09-16 19:35 Disputed
VLAI?
Summary
cryptlib through 3.4.4 allows a memory-cache side-channel attack on DSA and ECDSA signatures, aka the Return Of the Hidden Number Problem or ROHNP. To discover a key, the attacker needs access to either the local machine or a different virtual machine on the same physical host. NOTE: the vendor does not include side-channel attacks within its threat model
Severity ?
