  - FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license.
    This issue affects Clients only. Integer underflow leading to DOS (e.g. abort due to `WINPR_ASSERT` with     default compilation flags). When an insufficient blockLen is provided, and proper length validation is not     performed, an Integer Underflow occurs, leading to a Denial of Service (DOS) vulnerability. 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. (CVE-2023-39350)

  - FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license.
    Affected versions of FreeRDP are subject to a Null Pointer Dereference leading a crash in the RemoteFX     (rfx) handling. Inside the `rfx_process_message_tileset` function, the program allocates tiles using     `rfx_allocate_tiles` for the number of numTiles. If the initialization process of tiles is not completed     for various reasons, tiles will have a NULL pointer. Which may be accessed in further processing and would     cause a program 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. (CVE-2023-39351)

  - FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license.
    Affected versions are subject to an invalid offset validation leading to Out Of Bound Write. This can be     triggered when the values `rect->left` and `rect->top` are exactly equal to `surface->width` and     `surface->height`. eg. `rect->left` == `surface->width` && `rect->top` == `surface->height`. In practice     this should 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. (CVE-2023-39352)

  - 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. (CVE-2023-39353)

  - 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 `nsc_rle_decompress_data` function. The Out-     Of-Bounds Read occurs because it processes `context->Planes` without checking if it contains data of     sufficient length. Should an attacker be able to leverage this vulnerability they may be able to 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. (CVE-2023-39354)

  - FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license.
    Versions of FreeRDP on the 3.x release branch before beta3 are subject to a Use-After-Free in processing     `RDPGFX_CMDID_RESETGRAPHICS` packets. If `context->maxPlaneSize` is 0, `context->planesBuffer` will be     freed. However, without updating `context->planesBuffer`, this leads to a Use-After-Free exploit vector.
    In most environments this should only result in a crash. This issue has been addressed in version     3.0.0-beta3 and users of the beta 3.x releases are advised to upgrade. There are no known workarounds for     this vulnerability. (CVE-2023-39355)

  - FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license.
    In affected versions a missing offset validation may lead to an Out Of Bound Read in the function     `gdi_multi_opaque_rect`. In particular there is no code to validate if the value     `multi_opaque_rect->numRectangles` is less than 45. Looping through `multi_opaque_rect->`numRectangles     without proper boundary checks can lead to Out-of-Bounds Read errors which will likely lead to 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. (CVE-2023-39356)

  - FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license.
    Affected versions are subject 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 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. (CVE-2023-40181)

  - FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license.
    Affected versions are subject to an IntegerOverflow leading to Out-Of-Bound Write Vulnerability in the     `gdi_CreateSurface` function. This issue affects FreeRDP based clients only. FreeRDP proxies are not     affected as image decoding is not done by a proxy. 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. (CVE-2023-40186)

  - FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license.
    Affected versions of the 3.x beta branch are subject to a Use-After-Free issue in the     `avc420_ensure_buffer` and `avc444_ensure_buffer` functions. If the value of `piDstSize[x]` is 0,     `ppYUVDstData[x]` will be freed. However, in this case `ppYUVDstData[x]` will not have been updated which     leads to a Use-After-Free vulnerability. This issue has been addressed in version 3.0.0-beta3. Users of     the 3.x beta releases are advised to upgrade. There are no known workarounds for this vulnerability.
