CVE-2020-12460 not yet assigned priority: Debian including 1 source packages (opendmarc), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
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.
