Subject: CVE Request -- inn (nnrpd): Prone to STARTTLS plaintext command

Hello Kurt, Steve, vendors,

  the STARTTLS implementation in INN's NNTP server for readers,
nnrpd, before 2.5.3 does not properly restrict I/O buffering,
which allows man-in-the-middle attackers to insert commands
into encrypted sessions by sending a cleartext command that
is processed after TLS is in place, related to a "plaintext
command injection" attack, a similar issue to CVE-2011-0411.


Relevant upstream patch
(the 'diff -Nurp inn-2.5.2/nnrpd/misc.c inn-2.5.3/nnrpd/misc.c' part):

Could you allocate a CVE id for this?

Thank you && Regards, Jan.
