En bref Sévérité MEDIUM 4.7 EPSS EPSS 0.26 % · centile 17 (2026-10-27) État PUBLISHED Publiée 2023-12-27 Mise à jour 2025-11-03 Attribuée par redhat Statut NVD Modified
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.
