Name of the Vulnerable Software and Affected Versions FreeRDP versions prior to 2.11.0 FreeRDP versions prior to 3.0.0-beta3

Description The issue is related to 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 can be exploited by a remote attacker to cause a denial of service.

Recommendations For versions prior to 2.11.0, upgrade to version 2.11.0 or later. For versions prior to 3.0.0-beta3, upgrade to version 3.0.0-beta3 or later. As a temporary workaround, consider disabling the ncrush decompress function until a patch is available.
