high Nessus Plugin ID 227525

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - 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 relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
