CVE-2020-12460 (GCVE-0-2020-12460)

Vulnerability from cvelistv5 – Published: 2020-07-27 22:52 – Updated: 2024-08-04 11:56

Summary

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.
