The Slackware Linux team has released updated `sudo` packages for Slackware 15.0 and the -current version to address critical security vulnerabilities. The updates include version 1.9.17p1, which resolves issues that could potentially allow local privilege escalation attacks through the use of the `-h` (host) and `-R` (chroot) options in `sudo`. Specifically, if the sudoers file permits a user to execute commands on a different host, it could lead to unauthorized command execution as root, even bypassing the sudoers file. The chroot support, which is linked to this vulnerability, is set to be deprecated and removed in future releases.
