In FreeRDP before version 2.1.2, there is an out-of-bound read in glyph_cache_put. This affects all FreeRDP clients with +glyph-cache option enabled This is fixed in version 2.1.2.

Mitigation

Do not use the +glyph_cache option in the freerdp client, which is disabled by default in freerdp-2.0.0.rc4 (shipped with Red Hat Enterprise Linux 7 and 8), but required to connect to xrdp.
