CVE-2024-39929  (opens in a new tab)

How to fix?

Upgrade Debian:13 exim4 to version 4.98~RC3-2 or higher.

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:13 relevant fixed versions and status.

Exim through 4.97.1 misparses a multiline RFC 2231 header filename, and thus remote attackers can bypass a $mime_filename extension-blocking protection mechanism, and potentially deliver executable attachments to the mailboxes of end users.
