A read 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 the malicious certificate or for the application to con...
A cryptographic vulnerability exists in Node.js <19.2.0, <18.14.1, <16.19.1, <14.21.3 that in some cases did does not clear the OpenSSL error stack after operations that may set it. This may lead to false positive errors during subsequent cryptographic operations that happen to b...
sgx-dcap-quote-verify-python includes a statically linked copy of OpenSSL. The version of OpenSSL included in sgx-dcap-quote-verify-python 0.0.1..0.0.2 is vulnerable to a security issue. More details about the OpenSSL vulnerabilities themselves can be found at https://www.openssl...
A null pointer in OpenSSL can be dereferenced when signatures are being verified in malformed PKCS7 data. Agents or clients compiled with OpenSSL may experience unexpected crashes. OpenSSL has been removed in bottlerocket/update-operator version 1.1.0 in favor of Rust-based TLS u...
A timing based side channel exists in the OpenSSL RSA decryption implementation which could enable a recovery of plaintext from across the network. This affects all RSA padding modes. A server agent compiled with OpenSSL could be made to give up plaintext payloads over the networ...
A double-free vulnerability exists in OpenSSL where it is possible to construct a malicious PEM file that has 0 bytes of payload data. This then points to data that has already been freed in memory which, when freed again, leads to a crash. Agents or clients compiled with OpenSSL...
A read buffer overflow can be triggered in OpenSSL X.509 verification during name constraint checking. Note that this occurs after the certificate chain has been verified and would require a compromised CA. This can cause a client or agent compiled with OpenSSL to crash unexpecte...
An OpenSSL public API provides streaming of ASN.1 data via a BIO. It is possible for a malicious third party to use the BIO to access unfreed memory pointers that are not cleaned up after execution of the API. Freeing these memory pointers will result in a crash. Agents and clien...
A timing based side channel exists in the OpenSSL RSA Decryption implementation which could be sufficient to recover a plaintext across a network in a Bleichenbacher style attack. To achieve a successful decryption an attacker would have to be able to send a very large number of...
The function PEM_read_bio_ex() reads a PEM file from a BIO and parses and decodes the "name" (e.g. "CERTIFICATE"), any header data and the payload data. If the function succeeds then the "name_out", "header" and "data" arguments are populated with pointers to buffers containing t...
The public API function BIO_new_NDEF is a helper function used for streaming ASN.1 data via a BIO. It is primarily used internally to OpenSSL to support the SMIME, CMS and PKCS7 streaming capabilities, but may also be called directly by end user applications. The function receive...
An invalid pointer dereference on read can be triggered when an application tries to load malformed PKCS7 data with the d2i_PKCS7(), d2i_PKCS7_bio() or d2i_PKCS7_fp() functions. The result of the dereference is an application crash which could lead to a denial of service attack....
An invalid pointer dereference on read can be triggered when an application tries to check a malformed DSA public key by the EVP_PKEY_public_check() function. This will most likely lead to an application crash. This function can be called on public keys supplied from untrusted so...
There is a type confusion vulnerability relating to X.400 address processing inside an X.509 GeneralName. X.400 addresses were parsed as an ASN1_STRING but the public structure definition for GENERAL_NAME incorrectly specified the type of the x400Address field as ASN1_TYPE. This...
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 initializat...
This vulnerability allows local attackers to escalate privileges on affected installations of Windscribe. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the conf...
Mozilla VPN can load an OpenSSL configuration file from an unsecured directory. A user or attacker with limited privileges could leverage this to launch arbitrary code with SYSTEM privilege. This vulnerability affects Mozilla VPN < 2.7.1.
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 process...
The Diffie-Hellman Key Agreement Protocol allows use of long exponents that arguably make certain calculations unnecessarily expensive, because the 1996 van Oorschot and Wiener paper found that "(appropriately) short exponents" can be used when there are adequate subgroup constra...
pyca/cryptography's wheels include a statically linked copy of OpenSSL. The versions of OpenSSL included in cryptography 37.0.0-38.0.3 are vulnerable to a number of security issues. More details about the vulnerabilities themselves can be found in https://www.openssl.org/news/sec...
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 the malicious certificate or for the application to continue...

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...
