Description Srikanth Balasubramanian 2026-10-26 14:33:31 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

FreeRDP 3.0.0 before 3.32.0 contains an improper restriction of excessive authentication attempts in its virtual smartcard GIDS implementation, which stores the PIN retry counter per-handle. A malicious RDP server can exhaust the counter with VERIFY APDUs, then request a new SCardConnect to reset attempts, enabling unbounded online brute-forcing of the configured smartcard PIN.
Comment 1 Ondrej Holy 2026-11-02 13:55:58 UTC 
This issue is fixed in FreeRDP 3.32.0. Fedora currently ships freerdp 3.32.2 in all supported branches (F43, F44, F45 and Rawhide), so this flaw is no longer present. Closing as ERRATA.
