Name of the Vulnerable Software and Affected Versions Paramiko versions prior to 2.10.1

Description The issue is related to a race condition in the write private key file function, which could allow unauthorized information disclosure due to synchronization errors when using a shared resource. This could potentially enable an attacker to access confidential information.

Recommendations For Paramiko versions prior to 2.10.1, update to version 2.10.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the write private key file function until a patch is available.
