CVE-2023-39353
Date: August 31, 2023
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.
