NVD Description
Note: Versions mentioned in the description apply only to the upstream exim4
package and not the exim4
package as distributed by Debian
.
See How to fix?
for Debian:11
relevant fixed versions and status.
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.
