Description Ganesh 2026-10-16 12:45:32 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 from 3.0.0 before 3.32.0 contains an uncontrolled resource consumption vulnerability in parse_nla_mode_pdu that allows unauthenticated attackers to exhaust server memory. Attackers can complete TLS and stream bytes not beginning with the DER SEQUENCE tag 0x30, causing unbounded receive buffer growth before NLA authentication.

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.
