    Package        : mutt
    Version        : 1.10.1-2.1+deb10u7
    CVE ID         : CVE-2023-4874 CVE-2023-4875
    Debian Bug     : 1051563

    Two 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 Debian 10 buster, these problems have been fixed in version
    1.10.1-2.1+deb10u7.

    We recommend that you upgrade your mutt packages.

    For the detailed security status of mutt please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/mutt
