Package: xdm Version: 1:1.1.11-3 Severity: normal Dear Maintainer,
When somebody tries to log in and fails, xdm writes the given user name in the system logs. Unfortunately, typing the password in the login field is a common mistake. When that happens, xdm logs it too. That leaves the password of an user in clear in the system logs. It is not very important, but still a little security concern since normally passwords are stored permanently on the system only in hashed form. The corresponding log line looks like this: Jul 26 11:32:31 hellroy xdm[1004]: LOGIN FAILURE ON :0, XXXXXXXXXXX (I have redacted the login that was actually a password.) It may be better to not log it at all, or maybe only log it when it matches an actual login name.
