CVE-2020-4032

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

Description The issue is related to an integer casting vulnerability in the update recv secondary order function of the FreeRDP protocol implementation. This vulnerability affects all clients with +glyph-cache /relax-order-checks enabled. The vulnerability is associated with a lack of proper data type conversion mechanism in the gdi SelectObject component, which may allow a remote attacker to impact data integrity.

Recommendations For versions prior to 2.1.2, update to version 2.1.2 to resolve the issue. As a temporary workaround, consider disabling the +glyph-cache /relax-order-checks feature until the update is applied.
