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.");
