FreeRDP is a free implementation of the Remote Desktop Protocol (RDP),
released under the Apache license. Affected versions are subject to a
missing offset validation leading to Out Of Bound Read. In the
libfreerdp/codec/rfx.c
file there is no offset validation in
tile->quantIdxY
, tile->quantIdxCb
, and tile->quantIdxCr
. As a result
crafted input can lead to an out of bounds read access which in turn will
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 vulnerability.
