Azure Linux 3.0 Security Update: python3 (CVE-2024-0397)

high Nessus Plugin ID 215955

Synopsis

The remote Azure Linux host is missing one or more security updates.

Description

The version of python3 installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-0397 advisory.

 - A defect was discovered in the Python ssl module where there is a memory race condition with the ssl.SSLContext methods cert_store_stats() and get_ca_certs(). The race condition can be triggered if the methods are called at the same time as certificates are loaded into the SSLContext, such as during the TLS handshake with a certificate directory configured. This issue is fixed in CPython 3.10.14, 3.11.9, 3.12.3, and 3.13.0a5. (CVE-2024-0397)

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

Solution

Update the affected packages.
