How to fix?

Upgrade Minimos:latest pgbouncer-oci-entrypoint to version 1.25.2-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream pgbouncer-oci-entrypoint package and not the pgbouncer-oci-entrypoint package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

The SCRAM code in PgBouncer before 1.25.2 did not check the return value of strlcat() correctly when building the contents of the SCRAM client-final-message. A malicious backend that sends a SCRAM server-final-message with a long nonce can trigger a stack overflow.
