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

Description The issue is related to an out of bounds read in the license read new or upgrade license packet component. A manipulated license packet can cause out of bound reads to an internal buffer, potentially allowing 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 license read new or upgrade license packet component until the update is applied.
