CVE-2024-37408: Libfprint Fprintd

High severity, CVSS 7.3. EPSS: 0.3% chance of exploitation in the next 30 days.

fprintd through 1.94.3 lacks a security attention mechanism, and thus unexpected actions might be authorized by "auth sufficient pam_fprintd.so" for Sudo. NOTE: the supplier disputes this because they believe issue resolution would involve modifying the PAM configuration to restrict pam_fprintd.so to front-ends that implement a proper attention mechanism, not modifying pam_fprintd.so or fprintd.

Affected products

• Libfprint Fprintd: up to and including 1.94.3
