Synopsis
========
A vulnerability has been discovered in ProFTPd which could result in
memory disclosure.
Background
==========
ProFTPD is an advanced and very configurable FTP server.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-ftp/proftpd < 1.3.7c >= 1.3.7c
Description
===========
ProFTPd unconditionally sends passwords to Radius servers for
authentication in multiples of 16 bytes. If a password is not of a
length that is a multiple of 16 bytes, ProFTPd will read beyond the end
of the password string and send bytes beyond the end of the string
buffer.
Impact
======
Radius servers used for authentication can receive the contents of the
ProFTPd process' memory.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All ProFTPd users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-ftp/proftpd-1.3.7c"
