Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS / 23.10 : python-cryptography vulnerabilities (USN-6673-1)

high Nessus Plugin ID 191499

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS / 23.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6673-1 advisory.

 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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected python-cryptography and / or python3-cryptography packages.
