CVE-2025-32463
CriticalCVSS 9.3KEVSummary
Sudo before 1.9.17p1 allows local users to obtain root access because /etc/nsswitch.conf from a user-controlled directory is used with the --chroot option.
Risk Assessment
A local user can escalate privileges to root, potentially leading to full system compromise and data integrity violation.
Recommendation
Upgrade Sudo to version 1.9.17p1 or later and restrict access to the --chroot option for unprivileged users.

A vulnerability in Sudo before version 1.9.17p1 allows listed users in the sudoers file to execute commands on unintended machines when the file specifies a host that is neither the current host nor ALL.
- CVE-1999-1496Low
Sudo version 1.5 on Debian Linux 2.1 and Red Hat 6.0 allows local users to determine the existence of arbitrary files by attempting to execute the target filename as a program, which generates different error messages when the file does not exist.
- CVE-1999-0958High
Sudo versions 1.5.x allow local users to execute arbitrary commands via a .. (dot dot) attack.
