Foresight: initscripts Print E-mail
User Rating:      How can I rate this item?
Posted by Bill Keys   
Previous versions of the initscripts package do not set sufficiently restrictive permissions on the /var/log/btmp file, leading to an information exposure issue in which users' passwords may be revealed to unprivileged users in cases when the passwords have been inadvertently entered as usernames at some login prompts.

Foresight Linux Essential Advisory: 2007-0060-1
Published: 2007-10-26

Rating: Trivial

Updated Versions:
    initscripts=/conary.rpath.com at rpl:devel//foresight.rpath.org at fl:1-devel//1/8.33-2.9-1
    group-dist=/foresight.rpath.org at fl:1-devel//1/1.4.1-0.1-10

Description:
    Previous versions of the initscripts package do not set sufficiently
    restrictive permissions on the /var/log/btmp file, leading to an
    information exposure issue in which users' passwords may be revealed to
    unprivileged users in cases when the passwords have been inadvertently
    entered as usernames at some login prompts.
    
    Because sshd detects the incorrect permissions on /var/log/btmp and
    thus does not log failed authentications (instead issuing a warning
    about the file permissions to /var/log/secure), and gdm does not
    log the user name, this vulnerability is generally limited to failed
    logins at the system text console or over a local serial port.
