tag_insight = "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.";
