Debian Security Advisory DSA-2233-1 [email protected]
http://www.debian.org/security/ Florian Weimer
May 10, 2011 http://www.debian.org/security/faq
Package : postfix
Vulnerability : several
Problem type : remote
Debian-specific: no
CVE ID : CVE-2009-2939 CVE-2011-0411 CVE-2011-1720
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.
