Debian Bug : 1051563

Several NULL pointer dereference flaws were discovered in Mutt, a
text-based mailreader supporting MIME, GPG, PGP and threading, which may
result in denial of service (application crash) when viewing a specially
crafted email or when composing from a specially crafted draft message.

For the oldstable distribution (bullseye), these problems have been fixed
in version 2.0.5-4.1+deb11u3.

For the stable distribution (bookworm), these problems have been fixed in
version 2.2.9-1+deb12u1.

We recommend that you upgrade your mutt packages.
