    Package        : freerdp2     Version        : 2.3.0+dfsg1-2+deb10u4     CVE ID         : CVE-2021-41160 CVE-2022-24883 CVE-2022-39282 CVE-2022-39283                      CVE-2022-39316 CVE-2022-39318 CVE-2022-39319 CVE-2022-39347                      CVE-2022-41877

    Debian Bug     : 1001062 1021659

    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.

    CVE-2022-39319

        Affected versions of FreeRDP are missing input length validation in the         `urbdrc` channel. A malicious server can trick a FreeRDP based client to read         out of bound data and send it back to the server.

    CVE-2022-39347

        Affected versions of FreeRDP are missing path canonicalization and base path         check for `drive` channel. A malicious server can trick a FreeRDP based client         to read files outside the shared directory.

    CVE-2022-41877

        Affected versions of FreeRDP are missing input length validation in `drive`         channel. A malicious server can trick a FreeRDP based client to read out of         bound data and send it back to the server.


    For Debian 10 buster, these problems have been fixed in version     2.3.0+dfsg1-2+deb10u4.
