Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

A vulnerability has been found in Trusted Domain Project OpenDMARC up to 1.4.2. This affects the function opendmarc_policy_parse_dmarc in the library libopendmarc/opendmarc_policy.c. The manipulation of the argument fo/rf/ri/pct/sp/adkim/aspf/rua/ruf leads to handling of exceptional conditions. Remote exploitation of the attack is possible. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
