https://notcve.org/view.php?id=CVE-2020-1968
09 Sep 2020 — The Raccoon attack exploits a flaw in the TLS specification which can lead to an attacker being able to compute the pre-master secret in connections which have used a Diffie-Hellman (DH) based ciphersuite. In such a case this would result in the attacker being able to eavesdrop on all encrypted communications sent over that TLS connection. The attack can only be exploited if an implementation re-uses a DH secret across multiple TLS connections. Note that this issue only impacts DH ciphersuites and not ECDH ... • https://lists.debian.org/debian-lts-announce/2020/09/msg00016.html • CWE-203: Observable Discrepancy •

The outcome is that a valid certificate is never accepted (only a malformed certificate may be accepted).

CVSS: 5.3EPSS: 4%CPEs: 18EXPL: 0CVE-2019-1551 – rsaz_512_sqr overflow bug on x86_64
https://notcve.org/view.php?id=CVE-2019-1551
06 Dec 2019 — There is an overflow bug in the x64_64 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH512 are considered just feasible. However, for an attack the target would have to re-use the DH512 private key, which is not recommended anyway. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00030.html • CWE-190: Integer Overflow or Wraparound •

https://notcve.org/view.php?id=CVE-2019-1547
10 Sep 2019 — Normally in OpenSSL EC groups always have a co-factor present and this is used in side channel resistant code paths. However, in some cases, it is possible to construct a group using explicit parameters (instead of using a named curve). In those cases it is possible that such a group does not have the cofactor present. This can occur even where all the parameters match a known named curve. If such a curve is used then OpenSSL falls back to non-side channel resistant code paths which may result in full key r... • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00054.html • CWE-602: Client-Side Enforcement of Server-Side Security •

10 Sep 2019 — In situations where an attacker receives automated notification of the success or failure of a decryption attempt an attacker, after sending a very large number of messages to be decrypted, can recover a CMS/PKCS7 transported encryption key or decrypt any RSA encrypted message that was encrypted with the public RSA key, using a Bleichenbacher padding oracle attack.

30 Jul 2019 — OpenSSL has internal defaults for a directory tree where it can find a configuration file as well as certificates used for verification in TLS. This directory is most commonly referred to as OPENSSLDIR, and is configurable with the --prefix / --openssldir configuration options. For OpenSSL versions 1.1.0 and 1.1.1, the mingw configuration targets assume that resulting programs and libraries are installed in a Unix-like environment and the default prefix for program installation as well as for OPENSSLDIR sho... • https://cert-portal.siemens.com/productcert/pdf/ssa-412672.pdf • CWE-295: Improper Certificate Validation •

https://notcve.org/view.php?id=CVE-2019-1559
26 Feb 2019 — If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data.
