GitHub Vulnerability Alerts
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.
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.

CVE-2023-49083
Summary
Calling
load_pem_pkcs7_certificates
orload_der_pkcs7_certificates
could lead to a NULL-pointer dereference and segfault.PoC
Here is a Python code that triggers the issue:
Impact
Exploitation of this vulnerability poses a serious risk of Denial of Service (DoS) for any application attempting to deserialize a PKCS7 blob/certificate. The consequences extend to potential disruptions in system availability and stability.
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.
CVE-2024-26130
If
pkcs12.serialize_key_and_certificates
is called with both:encryption_algorithm
withhmac_hash
set (viaPrivateFormat.PKCS12.encryption_builder().hmac_hash(...)
Then a NULL pointer dereference would occur, crashing the Python process.
This has been resolved, and now a
ValueError
is properly raised.Patched in https://github.com/pyca/cryptography/pull/10423
