Package : sudo Version : 1.8.27-1+deb10u6 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.

CVE-2023-28486

Sudo did not escape control characters in log messages.

CVE-2023-28487

Sudo did not escape control characters in sudoreplay output.

For Debian 10 buster, these problems have been fixed in version 1.8.27-1+deb10u6.

We recommend that you upgrade your sudo packages.

For the detailed security status of sudo please refer to its security tracker page at:
