CVE-2024-37408
Publication date 8 June 2024
Last updated 4 August 2025
Ubuntu priority
Description
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.

mdeslaur
This isn't really a vulnerability in fprintd, it's a limitation when command-line applications use pam for authentication. See mailing list discussion, this CVE was disputed. Marking as not-affected.
