    Package        : sendmail
    Version        : 8.15.2-14~deb10u2
    CVE ID         : CVE-2023-51765
    Debian Bug     : 1059386

    sendmail allowed SMTP smuggling in certain configurations.
    Remote attackers can use a published exploitation technique to inject e-mail
    messages with a spoofed MAIL FROM address, allowing bypass
    of an SPF protection mechanism. This occurs because sendmail supports
    <LF>.<CR><LF> but some other popular e-mail servers do not.

    This particular injection vulnerability has been closed,
    unfortunatly full closure need to reject mail that
    contain NUL (0x00 byte).

    This is slighly non conformant with RFC and could
    be opt-out by setting confREJECT_NUL to 'false'
    in sendmail.mc file.

    For Debian 10 buster, this problem has been fixed in version
    8.15.2-14~deb10u2.

    We recommend that you upgrade your sendmail packages.

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