| CVE-2020-11098 | Low | 0.00 | 3.5 | 0.02 | Jun 22, 2020 | 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. | ||
| CVE-2020-11097 | Low | 0.00 | 3.5 | 0.01 | Jun 22, 2020 | In FreeRDP before version 2.1.2, an out of bounds read occurs resulting in accessing a memory location that is outside of the boundaries of the static array PRIMARY_DRAWING_ORDER_FIELD_BYTES. This is fixed in version 2.1.2. |
