Description Srikanth Balasubramanian 2026-10-28 08:43:39 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 a heap out-of-bounds read vulnerability that allows a malicious RD Gateway to crash clients by sending mismatched message lengths. Attackers controlling the gateway can set MsgBytes far larger than the NDR string ActualCount in consent or service messages, causing UTF-8 conversion to read past the stream allocation and disrupt client availability.
Comment 1 Ondrej Holy 2026-11-02 15:10:30 UTC 
Fixed in FreeRDP 3.32.0 (upstream). Fedora 43, 44, 45 and Rawhide ship freerdp 3.32.2, which contains the fix. Closing as ERRATA.
