Philipp Jeitner and Haya Shulman discovered a stack-based buffer overflow in libspf2, a library for validating mail senders with SPF, which could result in denial of service, or potentially execution of arbitrary code when processing a specially crafted SPF record.
For Debian 8 jessie, these problems have been fixed in version 1.2.10-5+deb8u1.
We recommend that you upgrade your libspf2 packages.
