Summary

Red Hat Security Advisory: python3.12-cryptography security update

Notes

Topic

An update for python3.12-cryptography is now available for Red Hat Enterprise Linux 9. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Details

Python is an interpreted, interactive, object-oriented programming language, which includes modules, classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to many system calls and libraries, as well as to various windowing systems. Security Fix(es): * python-cryptography: NULL pointer dereference with pkcs12.serialize_key_and_certificates when called with a non-matching certificate and private key and an hmac_hash override (CVE-2024-26130) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

While the vulnerability can result in a denial-of-service (DoS) by crashing the Python process, it requires specific conditions to trigger: a mismatch between the provided certificate\u0027s public key and private key, coupled with the use of an encryption algorithm with hmac_hash set.\n\nThe exploitation of this vulnerability does not directly lead to arbitrary code execution or data leakage. Instead, it causes a controlled termination of the Python process, which, although disruptive, is not as critical as other vulnerabilities that can lead to unauthorized access, data corruption, or code injection. However, it\u0027s important to note that denial-of-service conditions can still have operational impacts, disrupting services or causing system instability.\n\nThis issue does not affect Red Hat Enterprise Linux 6, 7, 8 and 9 as we dont ship the vulnerable code and package version.",

CVE-2024-26130 (GCVE-0-2024-26130)

Vulnerability from cvelistv5

Published

Modified

Severity ?

7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

CWE

CWE-476 - NULL Pointer Dereference

Summary

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Starting in version 38.0.0 and prior to version 42.0.4, if `pkcs12.serialize_key_and_certificates` is called with both a certificate whose public key did not match the provided private key and an `encryption_algorithm` with `hmac_hash` set (via `PrivateFormat.PKCS12.encryption_builder().hmac_hash(...)`, then a NULL pointer dereference would occur, crashing the Python process. This has been resolved in version 42.0.4, the first version in which a `ValueError` is properly raised.
