Package        : opendkim
Version        : 2.11.0~alpha-12+deb10u1
CVE ID         : CVE-2022-48521
Debian Bug     : 1041107

An issue (CVE-2022-48521) was discovered in OpenDKIM through 2.10.3, and
2.11.x through 2.11.0-Beta2. It fails to keep track of ordinal numbers
when removing fake Authentication-Results header fields, which allows a
remote attacker to craft an e-mail message with a fake sender address
such that programs that rely on Authentication-Results from OpenDKIM
will treat the message as having a valid DKIM signature when in fact it
has none.

For Debian 10 buster, this problem has been fixed in version

We recommend that you upgrade your opendkim packages.
