FreeRDP is a free implementation of the Remote Desktop Protocol (RDP),
released under the Apache license. Affected versions are subject to an
Out-Of-Bounds Read in the general_LumaToYUV444 function. This
Out-Of-Bounds Read occurs because processing is done on the in variable
without checking if it contains data of sufficient length. Insufficient
data for the in variable may cause errors or crashes. 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.
