  2. Vulnerabilities (CVE)
  3. CVE-2023-4641
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.

Summary
  • (es) Se encontró una falla en Shadow-Utils. Al solicitar una nueva contraseña, Shadow-Utils la solicita dos veces. Si la contraseña falla en el segundo intento, Shadow-Utils no logra limpiar el búfer utilizado para almacenar la primera entrada. Esto puede permitir que un atacante con suficiente acceso recupere la contraseña de la memoria.
