Base vector

AV:N/AC:M/Au:S/C:P/I:P/A:P

Name of the Vulnerable Software and Affected Versions FreeRDP versions prior to 2.1.0

Description The issue is related to an out-of-bound read in irp functions, specifically in parallel process irp create, serial process irp create, drive process irp write, printer process irp write, rdpei recv pdu, and serial process irp write. This can potentially allow a remote attacker to impact the confidentiality, integrity, and availability of protected information.

Recommendations For FreeRDP versions prior to 2.1.0, update to version 2.1.0 to resolve the issue. As a temporary workaround, consider disabling the affected irp functions until a patch is available. Restrict access to the vulnerable components to minimize the risk of exploitation. Avoid using the vulnerable functions in the affected versions until the issue is resolved.
