Name of the Vulnerable Software and Affected Versions FreeRDP versions prior to 2.1.2

Description The issue is related to an out of bound read in the PRIMARY DRAWING ORDER FIELD BYTES array, which can result in accessing a memory location outside of the array's boundaries. This can potentially allow a remote attacker to access confidential data and cause a denial of service.

Recommendations For versions prior to 2.1.2, update to version 2.1.2 to resolve the issue. As a temporary workaround, consider restricting access to the PRIMARY DRAWING ORDER FIELD BYTES array until a patch is available.
