The Gentoo Nullmailer package before 1.11-r2 uses world-readable permissions for /etc/nullmailer/remotes, which allows local users to obtain SMTP authentication credentials by reading the file.
file/edit_html.cgi in Webmin 1.590 and earlier does not perform an authorization check before showing a file's unedited contents, which allows remote attackers to read arbitrary files via the file field.
The ebuild of Webmin before 1.170-r3 on Gentoo Linux includes the encrypted root password in the miniserv.users file when building a tbz2 of the webmin package, which allows remote attackers to obtain and possibly crack the encrypted password.
The default configuration of Firebird before 2.0.3.12981.0-r6 on Gentoo Linux sets the ISC_PASSWORD environment variable before starting Firebird, which allows remote attackers to bypass SYSDBA authentication and obtain sensitive database information via an empty password.
