Last modified
CVE-2023-4641 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. A flaw was found in shadow-utils. When asking for a new password, shadow-utils asks the password twice. EPSS estimates a 0.26% chance of exploitation in the next 30 days.
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.
