CVSS: 7.8EPSS: 0%CPEs: 2EXPL: 0CVE-2023-0401 – NULL dereference during PKCS7 data verification
https://notcve.org/view.php?id=CVE-2023-0401
07 Feb 2023 — A NULL pointer can be dereferenced when signatures are being verified on PKCS7 signed or signedAndEnveloped data. In case the hash algorithm used for the signature is known to the OpenSSL library but the implementation of the hash algorithm is not available the digest initialization will fail. There is a missing check for the return value from the initialization function which later leads to invalid usage of the digest API most likely leading to a crash. The unavailability of an algorithm can be caused by u... • https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=d3b6dfd70db844c4499bec6ad6601623a565e674 • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2022-3996
13 Dec 2022 — If an X.509 certificate contains a malformed policy constraint and policy processing is enabled, then a write lock will be taken twice recursively. On some operating systems (most widely: Windows) this results in a denial of service when the affected process hangs. Policy processing being enabled on a publicly facing server is not considered to be a common setup. Policy processing is enabled by passing the `-policy' argument to the command line utilities or by calling the `X509_VERIFY_PARAM_set1_policies()'... • https://github.com/openssl/openssl/commit/7725e7bfe6f2ce8146b6552b44e0d226be7638e7 • CWE-667: Improper Locking •

01 Nov 2022 — A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed a malicious certificate or for an application to continue certificate verification despite failure to construct a path to a trusted issuer.

https://notcve.org/view.php?id=CVE-2022-3358
11 Oct 2022 — OpenSSL supports creating a custom cipher via the legacy EVP_CIPHER_meth_new() function and associated function calls. This function was deprecated in OpenSSL 3.0 and application authors are instead encouraged to use the new provider mechanism in order to implement custom ciphers. OpenSSL versions 3.0.0 to 3.0.5 incorrectly handle legacy custom ciphers passed to the EVP_EncryptInit_ex2(), EVP_DecryptInit_ex2() and EVP_CipherInit_ex2() functions (as well as other similarly named encryption and decryption ini... • https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=5485c56679d7c49b96e8fc8ca708b0b7e7c03c4b • CWE-476: NULL Pointer Dereference •

05 Jul 2022 — AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimised implementation will not encrypt the entirety of the data under some circumstances. This could reveal sixteen bytes of data that was preexisting in the memory that wasn't written. In the special case of "in place" encryption, sixteen bytes of the plaintext would be revealed. Since OpenSSL does not support OCB based cipher suites for TLS and DTLS, they are both unaffected.

01 Jul 2022 — The OpenSSL 3.0.4 release introduced a serious bug in the RSA implementation for X86_64 CPUs supporting the AVX512IFMA instructions. This issue makes the RSA implementation with 2048 bit private keys incorrect on such machines and memory corruption will happen during the computation. As a consequence of the memory corruption an attacker may be able to trigger a remote code execution on the machine performing the computation.

https://notcve.org/view.php?id=CVE-2022-1343
03 May 2022 — The function `OCSP_basic_verify` verifies the signer certificate on an OCSP response. In the case where the (non-default) flag OCSP_NOCHECKS is used then the response will be positive (meaning a successful verification) even in the case where the response signing certificate fails to verify. It is anticipated that most users of `OCSP_basic_verify` will not use the OCSP_NOCHECKS flag. In this case the `OCSP_basic_verify` function will return a negative value (indicating a fatal error) in the case of a certif... • https://cert-portal.siemens.com/productcert/pdf/ssa-953464.pdf • CWE-295: Improper Certificate Validation •
