CWEhttps://cwe.mitre.org/data/definitions/134.html

Format string vulnerability in the dkim_exim_verify_finish function in src/dkim.c in Exim before 4.76 might allow remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via format string specifiers in data used in DKIM logging, as demonstrated by an identity field containing a % (percent) character.

Weakness

The product uses a function that accepts a format string as an argument, but the format string originates from an external source.
