Summary
python-cryptography vulnerabilities
Details
Hubert Kario discovered that python-cryptography incorrectly handled errors returned by the OpenSSL API when processing incorrect padding in RSA PKCS#1 v1.5. A remote attacker could possibly use this issue to expose confidential or sensitive information. (CVE-2023-50782)
It was discovered that python-cryptography incorrectly handled memory operations when processing mismatched PKCS#12 keys. A remote attacker could possibly use this issue to cause python-cryptography to crash, leading to a denial of service. This issue only affected Ubuntu 23.10. (CVE-2024-26130)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
