CVE ID         : CVE-2023-7090 CVE-2023-28486 CVE-2023-28487

Sudo, a program designed to allow a sysadmin to give limited
root privileges to users and log root activity, was vulnerable.

CVE-2023-7090

    A flaw was found in sudo in the handling of ipa_hostname, where
    ipa_hostname from /etc/sssd/sssd.conf was not propagated in sudo.
    Therefore, it leads to privilege mismanagement vulnerability in
    applications, where client hosts retain privileges even after
    retracting them.

    Sudo did not escape control characters in log messages.

CVE-2023-28487

    Sudo did not escape control characters in sudoreplay output.
