Debian Security Advisory DSA-1659-1 security@debian.org

- ------------------------------------------------------------------------

Package : libspf2
Vulnerability : buffer overflow
Problem type : remote
Debian-specific: no
CVE Id(s) : CVE-2008-2469

Dan Kaminsky discovered that libspf2, an implementation of the Sender
Policy Framework (SPF) used by mail servers for mail filtering, handles
malformed TXT records incorrectly, leading to a buffer overflow
condition (CVE-2008-2469).

Note that the SPF configuration template in Debian's Exim configuration
recommends to use libmail-spf-query-perl, which does not suffer from
this issue.

For the stable distribution (etch), this problem has been fixed in
version 1.2.5-4+etch1.

For the testing distribution (lenny), this problem has been fixed in
version 1.2.5.dfsg-5+lenny1.

For the unstable distribution (sid), this problem will be fixed soon.

We recommend that you upgrade your libspf2 package.

Upgrade instructions
