Id Description
72156 Exim src/dkim.c dkim_exim_verify_finish() Function DKIM-Signature Header Form...

Exim is prone to a format string condition. The dkim_exim_verify_finish() function fails to properly sanitize format string specifiers (e.g., %s and %x) in the DKIM-Signature header. With a specially crafted email, a remote attacker can potentially cause arbitrary code execution.
