==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 20.04 LTS

- Ubuntu 16.04 LTS (Available with Ubuntu Pro)

Summary:

Several security issues were fixed in OpenDMARC.

Software Description:
- opendmarc: Open Source implementation of the DMARC specification

Details:

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)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 20.04 LTS:
   libopendmarc2                   1.3.2-7ubuntu0.1

   opendmarc                       1.3.2-3ubuntu0.2

Ubuntu 16.04 LTS (Available with Ubuntu Pro):
   libopendmarc2                   1.3.1+dfsg-3ubuntu0.1~esm1
