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 [MEDIUM] OpenDMARC vulnerabilities
Title: OpenDMARC vulnerabilities
Summary: Several security issues were fixed in OpenDMARC.
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)
Instructions: In general, a standard system update will make all the necessary changes.
