Package : libspf2
CVE ID : CVE-2021-20314
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 the stable distribution (buster), this problem has been fixed in
version 1.2.10-7.1~deb10u1.
We recommend that you upgrade your libspf2 packages.

tracker page at:
