leakage in the installer

Status in “ecryptfs-utils” source package in Ubuntu: Fix Released
Status in ecryptfs-utils in Ubuntu Jaunty: Fix Released

Bug description:
Binary package hint: ecryptfs-utils

The mount passphrase is leaked in the Ubuntu installer logs, at 
/var/log/installer/syslog.

This file is mode 0600:
-rw------- 1 syslog adm 347379 2009-06-04 11:00 /var/log/installer/syslog

However, it is written to the disk in the clear, and constitutes a leakage of 
the mount passphrase.

The upstream ecryptfs code (and Karmic) should be modified to support a flag to 
disable this printing, and the user-setup code should call 
ecryptfs-setup-private with this flag.

As for Jaunty, I'm attach a patch to ecryptfs-utils that should be uploaded to 
jaunty-security.  This patch uses sed to prune the offending lines out of 
/var/log/installer/syslog.

Please advise on whatever additional disclosure mechanisms (if any) need to be 
invoked (CVE, USN, etc.).
