NVD Description

Note: Versions mentioned in the description apply only to the upstream freerdp3 package and not the freerdp3 package as distributed by Ubuntu. See How to fix? for Ubuntu:26.04 relevant fixed versions and status.

FreeRDP versions before 3.31.0 contain an information disclosure vulnerability in the RDPGFX server's ResetGraphics PDU serializer that fails to initialize padding bytes in the fixed 340-byte wire format. Attackers can receive uninitialized heap memory including live pointers and GLib function addresses transmitted in the PDU, defeating heap ASLR and disclosing the GLib module base address.
