OpenDMARC through 1.3.2 and 1.4.x allows attacks that inject authentication results to provide false information about the domain that originated an e-mail message. This is caused by incorrect parsing and interpretation of SPF/DKIM authentication results, as demonstrated by the example.net(.example.com substring.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 937aa1d6-685e-11ec-a636-000c29061ce6 advisory.

  - OpenDMARC through 1.3.2 and 1.4.x through 1.4.0-Beta1 is prone to a signature-bypass vulnerability with     multiple From: addresses, which might affect applications that consider a domain name to be relevant to     the origin of an e-mail message. (CVE-2019-16378)

  - OpenDMARC through 1.3.2 and 1.4.x, when used with pypolicyd-spf 2.0.2, allows attacks that bypass SPF and     DMARC authentication in situations where the HELO field is inconsistent with the MAIL FROM field.
    (CVE-2019-20790)

  - OpenDMARC through 1.3.2 and 1.4.x allows attacks that inject authentication results to provide false     information about the domain that originated an e-mail message. This is caused by incorrect parsing and     interpretation of SPF/DKIM authentication results, as demonstrated by the example.net(.example.com     substring. (CVE-2020-12272)

  - OpenDMARC through 1.3.2 and 1.4.x through 1.4.0-Beta1 has improper null termination in the function     opendmarc_xml_parse that can result in a one-byte heap overflow in opendmarc_xml when parsing a specially     crafted DMARC aggregate report. This can cause remote memory corruption when a '\0' byte overwrites the     heap metadata of the next chunk and its PREV_INUSE flag. (CVE-2020-12460)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Ubuntu 16.04 ESM / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6356-1 advisory.

    Jianjun Chen, Vern Paxson and Jian Jiang discovered that OpenDMARC incorrectly handled certain inputs. If     a user or an automated system were tricked into receiving crafted inputs, an attacker could possibly use     this to falsify the domain of an e-mails origin. (CVE-2020-12272)

    Patrik Lantz discovered that OpenDMARC incorrectly handled certain inputs. If a user or an automated     system were tricked into opening a specially crafted input file, a remote attacker could possibly use this     issue to cause a denial of service. (CVE-2020-12460)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

The remote Debian 10 host has packages installed that are affected by a vulnerability as referenced in the dla-3546 advisory.
