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 an Integer-Underflow leading to Out-Of-Bound Read in the
zgfx decompress segment function. In the context of CopyMemory, it's possible to read data beyond the transmitted packet range and likely cause a crash. This can be exploited by a remote attacker to cause a denial of service.Recommendations
For FreeRDP versions prior to 2.11.0, upgrade to version 2.11.0 or later.
For FreeRDP versions prior to 3.0.0-beta3, upgrade to version 3.0.0-beta3 or later.
As a temporary workaround, consider restricting the use of the
zgfx decompress segment function until a patch is available.
Avoid using the CopyMemory function in the context of the zgfx decompress segment function until the issue is resolved.Exploit
