Alberto Bertogli	2612c8bfa1	dkim: Fail verification if l= is too large ... Currently, if the value of the l= tag is larger than the body, that causes an out-of-bound access and the server crashes. The RFC is clear that the value should be <= the size of the canonicalized body. This patch fixes the problem by validating the length appropriately, and returning a permanent failure if it's invalid. Thanks to John JEAN <john@wargan.com> who reported a similar issue (fixed in a previous patch), which led to finding this bug.	2026-10-09 21:32:22 +01:00
