| Package | Affected versions | Patched versions |
|---|---|---|
| exim | ≥ 4.00, < 4.94.2 | 4.94.2 |
Exim 4 before 4.94.2 allows Out-of-bounds Read because pdkim_finish_bodyhash does not validate the relationship between sig->bodyhash.len and b->bh.len; thus, a crafted DKIM-Signature header might lead to a leak of sensitive information from process memory.
