Package : exim4 CVE ID : CVE-2024-39929 Debian Bug : 1075785

Phillip Szelat discovered that Exim, a mail transport agent, does not properly parse a multiline RFC 2231 header filename, allowing a remote attacker to bypass a $mime_filename based extension-blocking protection mechanism.

For the oldstable distribution (bullseye), this problem has been fixed in version 4.94.2-7+deb11u3.

For the stable distribution (bookworm), this problem has been fixed in version 4.96-15+deb12u5.

We recommend that you upgrade your exim4 packages.
