CVE-2023-4641

Severity CVSS v4.0:
Pending analysis
Type:
Unavailable / Other
Publication date:

Description

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.
