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-2020-8945, which was previously fixed via RHSA-2020:2117. This issue could possibly be used to crash or cause potential code execution in Go applications that use the Go GPGME wrapper library, under certain conditions, during GPG signature verification.

Weakness

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
