CVE-2020-25659

RSA decryption was vulnerable to Bleichenbacher timing vulnerabilities, which would impact people using RSA decryption in online scenarios. This is fixed in cryptography 3.2.

CVE-2023-23931

Previously, Cipher.update_into would accept Python objects which implement the buffer protocol, but provide only immutable buffers:

>>> outbuf = b"\x00" * 32
>>> c = ciphers.Cipher(AES(b"\x00" * 32), modes.ECB()).encryptor()
>>> c.update_into(b"\x00" * 16, outbuf)
16
>>> outbuf
b'\xdc\x95\xc0x\xa2@&#8203;\x89\x89\xadH\xa2\x14\x92\x84 \x87\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00'

This would allow immutable objects (such as bytes) to be mutated, thus violating fundamental rules of Python. This is a soundness bug -- it allows programmers to misuse an API, it cannot be exploited by attacker controlled data alone.

This now correctly raises an exception.

This issue has been present since update_into was originally introduced in cryptography 1.8.

CVE-2023-0286

pyca/cryptography's wheels include a statically linked copy of OpenSSL. The versions of OpenSSL included in cryptography 0.8.1-39.0.0 are vulnerable to a security issue. More details about the vulnerabilities themselves can be found in https://www.openssl.org/news/secadv/20221213.txt and https://www.openssl.org/news/secadv/20230207.txt.

If you are building cryptography source ("sdist") then you are responsible for upgrading your copy of OpenSSL. Only users installing from wheels built by the cryptography project (i.e., those distributed on PyPI) need to update their cryptography versions.

GHSA-5cpq-8wj7-hf2v

pyca/cryptography's wheels include a statically linked copy of OpenSSL. The versions of OpenSSL included in cryptography 0.5-40.0.2 are vulnerable to a security issue. More details about the vulnerability itself can be found in https://www.openssl.org/news/secadv/20230530.txt.

GHSA-jm77-qphf-c4w8

pyca/cryptography's wheels include a statically linked copy of OpenSSL. The versions of OpenSSL included in cryptography 0.8-41.0.2 are vulnerable to several security issues. More details about the vulnerabilities themselves can be found in https://www.openssl.org/news/secadv/20230731.txt, https://www.openssl.org/news/secadv/20230719.txt, and https://www.openssl.org/news/secadv/20230714.txt.

GHSA-v8gr-m533-ghj9

pyca/cryptography's wheels include a statically linked copy of OpenSSL. The versions of OpenSSL included in cryptography 2.5-41.0.3 are vulnerable to several security issues. More details about the vulnerabilities themselves can be found in https://www.openssl.org/news/secadv/20230908.txt.

CVE-2023-50782

A flaw was found in the python-cryptography package. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which may lead to exposure of confidential or sensitive data.

CVE-2024-0727

Issue summary: Processing a maliciously formatted PKCS12 file may lead OpenSSL to crash leading to a potential Denial of Service attack

Impact summary: Applications loading files in the PKCS12 format from untrusted sources might terminate abruptly.

A file in PKCS12 format can contain certificates and keys and may come from an untrusted source. The PKCS12 specification allows certain fields to be NULL, but OpenSSL does not correctly check for this case. This can lead to a NULL pointer dereference that results in OpenSSL crashing. If an application processes PKCS12 files from an untrusted source using the OpenSSL APIs then that application will be vulnerable to this issue.

OpenSSL APIs that are vulnerable to this are: PKCS12_parse(), PKCS12_unpack_p7data(), PKCS12_unpack_p7encdata(), PKCS12_unpack_authsafes() and PKCS12_newpass().

We have also fixed a similar issue in SMIME_write_PKCS7(). However since this function is related to writing data we do not consider it security significant.

The FIPS modules in 3.2, 3.1 and 3.0 are not affected by this issue.
