NNTP Service STARTTLS Plaintext Command Injection

The remote news server contains a software flaw in its STARTTLS implementation that could allow a remote, unauthenticated attacker to inject commands during the plaintext protocol phase that will be executed during the ciphertext protocol phase. Successful exploitation could allow an attacker...

openSUSE Security Update : postfix (openSUSE-SU-2011:0389-1)

postfix did not clear the receive buffer after the STARTTLS command. A man-in-the middle could therefore inject commands in the unencrypted stream that get interpreted in the encrypted phase after STARTTLS CVE-2011-0411. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text an...

Multiple Products STARTTLS Plaintext Command Injection (CVE-2011-0411; CVE-2014-3556)

STARTTLS is an extension to plaintext communication protocols that offers a way to upgrade plain text communications to an encrypted TLS or SSL connection. Protocols such as SMTP and FTP can be TLS-secured with a compatible server by a client sending the STARTTLS command. A command injection...

fetchmail -- STARTTLS denial of service

Matthias Andree reports: Fetchmail version 5.9.9 introduced STLS support for POP3, version 6.0.0 added STARTTLS for IMAP. However, the actual STARTTLS-initiated in-band SSL/TLS negotiation was not guarded by a timeout. Depending on the operating system defaults as to TCP stream keepalive mode,...

postfix: SMTP commands injection during plaintext to TLS session switch

The STARTTLS implementation in Postfix 2.4.x before 2.4.16, 2.5.x before 2.5.12, 2.6.x before 2.6.9, and 2.7.x before 2.7.3 does not properly restrict I/O buffering, which allows man-in-the-middle attackers to insert commands into encrypted SMTP sessions by sending a cleartext command that is...

pureftpd -- multiple vulnerabilities

Pure-FTPd development team reports: Support for braces expansion in directory listings has been disabled -- Cf. CVE-2011-0418. Fix a STARTTLS flaw similar to Postfix's CVE-2011-0411. If you're using TLS, upgrading is recommended...
