The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - freerdp: Out-of-bounds write in rdp_recv_tpkt_pdu (CVE-2017-2835)

  - FreeRDP before 1.1.0-beta1 allows remote attackers to cause a denial of service (NULL pointer dereference     and application crash) via unspecified vectors. (CVE-2013-4118)

  - FreeRDP before 1.1.0-beta+2013071101 allows remote attackers to cause a denial of service (NULL pointer     dereference and application crash) by disconnecting before authentication has finished. (CVE-2013-4119)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3606 advisory.

  - In FreeRDP less than or equal to 2.0.0, by providing manipulated input a malicious client can create a     double free condition and crash the server. This is fixed in version 2.1.0. (CVE-2020-11017)

  - In FreeRDP less than or equal to 2.0.0, a possible resource exhaustion vulnerability can be performed.
    Malicious clients could trigger out of bound reads causing memory allocation with random size. This has     been fixed in 2.1.0. (CVE-2020-11018)

  - In FreeRDP less than or equal to 2.0.0, when running with logger set to WLOG_TRACE, a possible crash of     application could occur due to a read of an invalid array index. Data could be printed as string to local     terminal. This has been fixed in 2.1.0. (CVE-2020-11019)

  - In FreeRDP less than or equal to 2.0.0, an Integer Overflow to Buffer Overflow exists. When using /video     redirection, a manipulated server can instruct the client to allocate a buffer with a smaller size than     requested due to an integer overflow in size calculation. With later messages, the server can manipulate     the client to write data out of bound to the previously allocated buffer. This has been patched in 2.1.0.
    (CVE-2020-11038)

  - In FreeRDP less than or equal to 2.0.0, when using a manipulated server with USB redirection enabled     (nearly) arbitrary memory can be read and written due to integer overflows in length checks. This has been     patched in 2.1.0. (CVE-2020-11039)

  - In FreeRDP less than or equal to 2.0.0, there is an out-of-bound data read from memory in     clear_decompress_subcode_rlex, visualized on screen as color. This has been patched in 2.1.0.
    (CVE-2020-11040)

  - In FreeRDP less than or equal to 2.0.0, an outside controlled array index is used unchecked for data used     as configuration for sound backend (alsa, oss, pulse, ...). The most likely outcome is a crash of the     client instance followed by no or distorted sound or a session disconnect. If a user cannot upgrade to the     patched version, a workaround is to disable sound for the session. This has been patched in 2.1.0.
    (CVE-2020-11041)

  - In FreeRDP greater than 1.1 and before 2.0.0, there is an out-of-bounds read in update_read_icon_info. It     allows reading a attacker-defined amount of client memory (32bit unsigned -> 4GB) to an intermediate     buffer. This can be used to crash the client or store information for later retrieval. This has been     patched in 2.0.0. (CVE-2020-11042)

  - In FreeRDP less than or equal to 2.0.0, there is an out-of-bounds read in rfx_process_message_tileset.
    Invalid data fed to RFX decoder results in garbage on screen (as colors). This has been patched in 2.1.0.
    (CVE-2020-11043)

  - In FreeRDP greater than 1.2 and before 2.0.0, a double free in update_read_cache_bitmap_v3_order crashes     the client application if corrupted data from a manipulated server is parsed. This has been patched in     2.0.0. (CVE-2020-11044)

  - In FreeRDP after 1.0 and before 2.0.0, there is an out-of-bound read in in update_read_bitmap_data that     allows client memory to be read to an image buffer. The result displayed on screen as colour.
    (CVE-2020-11045)

  - In FreeRDP after 1.0 and before 2.0.0, there is a stream out-of-bounds seek in update_read_synchronize     that could lead to a later out-of-bounds read. (CVE-2020-11046)

  - In FreeRDP after 1.1 and before 2.0.0, there is an out-of-bounds read in     autodetect_recv_bandwidth_measure_results. A malicious server can extract up to 8 bytes of client memory     with a manipulated message by providing a short input and reading the measurement result data. This has     been patched in 2.0.0. (CVE-2020-11047)

  - In FreeRDP after 1.0 and before 2.0.0, there is an out-of-bounds read. It only allows to abort a session.
    No data extraction is possible. This has been fixed in 2.0.0. (CVE-2020-11048)

  - In FreeRDP after 1.1 and before 2.0.0, there is an out-of-bound read of client memory that is then passed     on to the protocol parser. This has been patched in 2.0.0. (CVE-2020-11049)

  - In FreeRDP after 1.1 and before 2.0.0, a stream out-of-bounds seek in rdp_read_font_capability_set could     lead to a later out-of-bounds read. As a result, a manipulated client or server might force a disconnect     due to an invalid data read. This has been fixed in 2.0.0. (CVE-2020-11058)

  - In FreeRDP before 2.1.0, there is an out-of-bounds read in cliprdr_read_format_list. Clipboard format data     read (by client or server) might read data out-of-bounds. This has been fixed in 2.1.0. (CVE-2020-11085)

  - In FreeRDP less than or equal to 2.0.0, there is an out-of-bound read in     ntlm_read_ntlm_v2_client_challenge that reads up to 28 bytes out-of-bound to an internal structure. This     has been fixed in 2.1.0. (CVE-2020-11086)

  - In FreeRDP less than or equal to 2.0.0, there is an out-of-bound read in ntlm_read_AuthenticateMessage.

  - 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 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-2023-40188)

  - 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 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-2023-40567)

  - 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 `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-2023-40569)

  - 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. (CVE-2023-40589)
