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.
