Package : opendmarc
Version : 1.3.2-6+deb10u3
CVE ID : CVE-2020-12272
Debian Bug : 977767
It was discovered that there was an issue in the opendmarc DMARC
email filter system. A vulnerability allowed attackers to inject
authentication results to provide false information about the domain
that originated an email message. This was caused by incorrect
parsing and interpretation of SPF/DKIM authentication results.
For Debian 10 buster, this problem has been fixed in version
1.3.2-6+deb10u3.
We recommend that you upgrade your opendmarc packages.
