Upgrade Debian:12 exim4 to version 4.34-10 or higher.

NVD Description

Note: Versions mentioned in the description apply to the upstream exim4 package. See How to fix? for Debian:12 relevant versions.

Multiple buffer overflows in Exim before 4.43 may allow attackers to execute arbitrary code via (1) an IPv6 address with more than 8 components, as demonstrated using the -be command line option, which triggers an overflow in the host_aton function, or (2) the -bh command line option or dnsdb PTR lookup, which triggers an overflow in the dns_build_reverse function.
