CVE-2020-12460 is fixed in 3 products on 1 platform, first by libopendmarc2 1.3.2-3ubuntu0.2, released July 27, 2020. It is not reported as exploited. Patch Radar priority: Routine.
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.
