A vulnerability, which was classified as critical, was found in Ubuntu passwd 1:4.0.13. This affects an unknown code block. The manipulation with an unknown input leads to a local privilege escalation vulnerability. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:
passwd before 1:4.0.13 on Ubuntu 6.06 LTS leaves the root password blank instead of locking it when the administrator selects the "Go Back" option after the final "Installation complete" message and uses the main menu, which causes the password to be zeroed out in the installer s memory.
