A flaw was found in FreeRDP. An out-of-bounds read vulnerability in the Remote Assistance file parser allows an attacker to cause a Denial of Service (DoS). By convincing a user to open a specially crafted Remote Assistance invitation file, the application mishandles memory bounds while processing the file data, resulting in an application crash.

Description OSIDB Bzimport 2026-10-12 16:50:57 UTC
FreeRDP 3.0.0 before 3.32.0 contains a heap out-of-bounds read in freerdp_assistance_parse_all_elements_of() because it advances its parsing cursor without reducing the remaining length, letting the scan window exceed the decrypted ConnectionString2 buffer. Attackers can supply a crafted .msrcIncident invitation file and password that crash xfreerdp when opened, before any RDP connection.
