Debian: New libspf2 packages fix potential remote code execution
Summary
- ------------------------------------------------------------------------Debian Security Advisory DSA-1659-1 security@debian.org http://www.debian.org/security/ Florian Weimer October 23, 2008 http://www.debian.org/security/faq - ------------------------------------------------------------------------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 - --------------------wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.
