The version of podman as released for Red Hat Enterprise Linux 7 Extras via RHSA-2022:2190 advisory included an incorrect version of podman missing the fix for CVE-2020-14370, which was previously fixed via RHSA-2020:5056. This issue could possibly allow an attacker to gain access to sensitive information stored in environment variables.

Weakness

The product stores sensitive information in cleartext within a resource that might be accessible to another control sphere.

Red Hat Enterprise Linux 7 Extras RedHat podman-0:1.6.4-36.el7_9 *

Extended Description

Because the information is stored in cleartext (i.e., unencrypted), attackers could potentially read it. Even if the information is encoded in a way that is not human-readable, certain techniques could determine which encoding is being used, then decode the information. When organizations adopt cloud services, it can be easier for attackers to access the data from anywhere on the Internet. In some systems/environments such as cloud, the use of “double encryption” (at both the software and hardware layer) might be required, and the developer might be solely responsible for both layers, instead of shared responsibility with the administrator of the broader system/environment.
