- ------------------------------------------------------------------------- Debian LTS Advisory DLA-4235-1 [email protected] https://www.debian.org/lts/security/ Thorsten Alteholz June 30, 2025 https://wiki.debian.org/LTS
- -------------------------------------------------------------------------

Package : sudo Version : 1.9.5p2-3+deb11u2 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 Debian 11 bullseye, this problem has been fixed in version 1.9.5p2-3+deb11u2.

We recommend that you upgrade your sudo packages.

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

Solution
