CVE-2022-48521
MEDIUM5.3EPSS 0.17%opendkim - security update
Published: 7/11/2023Modified: 4/28/2026
Description
An issue 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.
Affected packages (2)
- Debian/opendkimfrom 0, < 2.11.0~beta2-4+deb11u1
- Debian/opendkimfrom 0, < 2.11.0~alpha-12+deb10u1
