Debian DLA-2639-1 : opendmarc security update

critical Nessus Plugin ID 149014

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
