Debian LTS Advisory DLA-2639-1 [email protected]

Package : opendmarc
Version : 1.3.2-2+deb9u3
CVE ID : CVE-2020-12460
Debian Bug : 966464

It was discovered that OpenDMARC, a milter implementation of DMARC,
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.

For Debian 9 stretch, this problem has been fixed in version
1.3.2-2+deb9u3.

We recommend that you upgrade your opendmarc packages.

For the detailed security status of opendmarc please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/opendmarc
