Description Srikanth Balasubramanian 2026-10-28 08:40:01 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 2.3.0 before 3.32.0 contains an infinite loop vulnerability in http_chuncked_read that allows malicious RD Gateways to hang clients by sending incomplete chunked responses. Attackers can send a partial chunk-size line or footer followed by a clean TLS shutdown, causing zero-byte reads to loop forever and freeze the client decoder thread.

Comment 1 Ondrej Holy 2026-11-02 15:10:29 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.
