CVE-2024-39929

Publication date 4 July 2024

Last updated 31 July 2024

Ubuntu priority

Medium

Why this priority?

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.
