Synopsis
The remote Amazon Linux AMI host is missing a security update.Description
The version of shadow-utils installed on the remote host is prior to 4.1.4.2-13.11. It is, therefore, affected by a vulnerability as referenced in the ALAS-2023-1873 advisory.- 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.
(CVE-2023-4641) (CVE-2023-4641)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
