CWE-264  (opens in a new tab)

How to fix?

Upgrade Debian:unstable inn2 to version 2.5.3-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream inn2 package and not the inn2 package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

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" attack, a similar issue to CVE-2011-0411.
