FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. In affected versions there is a Global-Buffer-Overflow in the ncrush_decompress function. Feeding crafted input into this function can trigger the overflow which has only been shown to cause a crash. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this issue.
