CVE-2023-4641 Open this link in a new tabHow to fix?
Upgrade Oracle:8 shadow-utils to version 2:4.6-19.el8 or higher.
This issue was patched in ELSA-2023-7112.
NVD Description
Note: Versions mentioned in the description apply only to the upstream shadow-utils package and not the shadow-utils package as distributed by Oracle.
See How to fix? for Oracle:8 relevant fixed versions and status.
A flaw was found in shadow-utils. When asking for a new password, shadow-utils asks the password twice. If the password fails on the second attempt, shadow-utils fails in cleaning the buffer used to store the first entry. This may allow an attacker with enough access to retrieve the password from the memory.
