Package        : postfix-policyd
Vulnerability  : buffer overflow
Problem type   : remote
Debian-specific: no
CVE Id(s)      : CVE-2007-3791
Debian Bug     : 435735


It was discovered that postfix-policyd, an anti-spam plugin for postfix,
didn't correctly bounds-test incoming SMTP commands potentially allowing
the remote exploitation of arbitrary code.

For the stable distribution (etch), this problem has been fixed in version
1.80-2.1etch1.

For the old stable distribution (sarge), this package was not present.

For the unstable distribution (sid), this problem was fixed in version
1.80-2.2.

We recommend that you upgrade your postfix-policyd package.
