CVE-2023-39353: Missing offset validation leading to Out Of Bound Read

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.

#vulnerability #mac #apache #c++

Affected versions

<= 2.10.0 , <= 3.0.0-beta2

Patched versions

2.11.0, 3.0.0-beta3

Summary

Missing offset validation leading to Out Of Bound Read

Affected

FreeRDP based clients only. FreeRDP proxy not affected as image decoding is not done by proxy (data passthrough)

Details

Stream_Read_UINT8(sub, tile->quantIdxY); /* quantIdxY (1 byte) */

Stream_Read_UINT8(sub, tile->quantIdxCb); /* quantIdxCb (1 byte) */

Stream_Read_UINT8(sub, tile->quantIdxCr); /* quantIdxCr (1 byte) */

There’re no offset validation in tile->quantIdxY, tile->quantIdxCb, tile->quantIdxCr.

PoC

Set tile->quantIdxY >= context->numQuant

Impact

Out Of Bound Read
