Debian Security Advisory

DSA-1659-1 libspf2 -- buffer overflow

Date Reported:
23 Oct 2008
Affected Packages:
libspf2
Vulnerable:
Yes
Security database references:
In Mitre's CVE dictionary: CVE-2008-2469.
More information:

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.

Fixed in:

Debian GNU/Linux 4.0 (etch)
