    Multiple vulnerabilties have been found in freelrdp2, a free     implementation of the Remote Desktop Protocol (RDP). The vulnerabilties     potentially allows authentication bypasses on configuration errors,     buffer overreads, DoS vectors, buffer overflows or accessing files     outside of a shared directory.

    CVE-2021-41160

        In affected versions a malicious server might trigger out of bound         writes in a connected client. Connections using GDI or SurfaceCommands         to send graphics updates to the client might send `0` width/height or         out of bound rectangles to trigger out of bound writes. With `0` width         or heigth the memory allocation will be `0` but the missing bounds         checks allow writing to the pointer at this (not allocated) region.

    CVE-2022-24883

        Prior to version 2.7.0, server side authentication against a `SAM` file         might be successful for invalid credentials if the server has configured         an invalid `SAM` file path. FreeRDP based clients are not affected. RDP         server implementations using FreeRDP to authenticate against a `SAM`         file are affected. Version 2.7.0 contains a fix for this issue. As a         workaround, use custom authentication via `HashCallback` and/or ensure         the `SAM` database path configured is valid and the application has file         handles left.

    CVE-2022-39282

        FreeRDP based clients on unix systems using `/parallel` command line         switch might read uninitialized data and send it to the server the         client is currently connected to. FreeRDP based server implementations         are not affected.

    CVE-2023-39283

        All FreeRDP based clients when using the `/video` command line switch         might read uninitialized data, decode it as audio/video and display the         result.  FreeRDP based server implementations are not affected.

    CVE-2022-39316

        In affected versions there is an out of bound read in ZGFX decoder         component of FreeRDP. A malicious server can trick a FreeRDP based         client to read out of bound data and try to decode it likely resulting         in a crash.

    CVE-2022-39318

        Affected versions of FreeRDP are missing input validation in `urbdrc`         channel.  A malicious server can trick a FreeRDP based client to crash         with division by zero.

        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-2023-39351

        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-2023-39352

        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-2023-39353

        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-2023-39354

        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-2023-39355

        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-2023-39356

        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.

    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-2023-39354:
    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-2023-39356:
    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-2023-40181:
    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-2023-40186:
    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-2023-40188:
    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.

    CVE-2023-40567:
    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 Write in the `clear_decompress_bands_data` function in     which there is no offset validation. Abuse of this vulnerability may lead to an out of bounds write. 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-2023-40569:
    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 Write in the `progressive_decompress` function. This     issue is likely down to incorrect calculations of the `nXSrc` and `nYSrc` variables. 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-2023-40589:
    FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license.
    In affected versions there is a Global-Buffer-Overflow in the ncrush_decompress function. Feeding crafted     input into this function can trigger the overflow which has only been shown 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 issue.
