CVE-2012-3523 low priority: Debian including 2 source packages (inn, inn2), 10 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 10.
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.
