    Several vulnerabilities were discovered in Postfix, a mail transfer
    agent.  The Common Vulnerabilities and Exposures project identifies
    the following problems:
    
    CVE-2009-2939
            The postinst script grants the postfix user write access to
            /var/spool/postfix/pid, which might allow local users to
            conduct symlink attacks that overwrite arbitrary files.
    
    CVE-2011-0411
            The STARTTLS implementation 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 processed after TLS is in place.
    
    CVE-2011-1720
            A heap-based read-only buffer overflow allows malicious
            clients to crash the smtpd server process using a crafted SASL
            authentication request.
    
    For the oldstable distribution (lenny), this problem has been fixed in
    version 2.5.5-1.1+lenny1.
    
    For the stable distribution (squeeze), this problem has been fixed in
    version 2.7.1-1+squeeze1.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 2.8.0-1.
    
    We recommend that you upgrade your postfix packages.
