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 before 3.32.2 contains a denial of service vulnerability that allows malicious servers or unauthenticated peers to abort clients or proxies via oversized X.224 routing tokens. Attackers can send an oversized LoadBalanceInfo in a Server Redirection PDU, or a 240–247 byte token to a FixedTarget freerdp-proxy, triggering a tpdu_write_header assertion that crashes the process.
