 Package : sudo CVE ID : CVE-2025-32462

 Rich Mirch discovered that sudo, a program designed to provide limited super user privileges to specific users, does not correctly handle the host (-h or --host) option. Due to a bug the host option was not restricted to listing privileges only and could be used when running a command via sudo or editing a file with sudoedit. Depending on the rules present in the sudoers file the flaw might allow a local privilege escalation attack.

 For the stable distribution (bookworm), this problem has been fixed in version 1.9.13p3-1+deb12u2.

 We recommend that you upgrade your sudo packages.

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