GLSA-201401-24 : INN: Man-in-the-middle attack

The remote host is affected by the vulnerability described in GLSA-201401-24 INN: Man-in-the-middle attack INNs I/O buffering is not correctly restricted. Impact : A remote attacker could inject commands into encrypted NNTP sessions. Workaround : There is no known workaround at this time...

Command injection

The STARTTLS implementation in nnrpd in INN 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"...
