The version of freerdp installed on the remote host is prior to 2.1.1-2. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2020-1516 advisory.

    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.
    This has been fixed in 2.1.0. (CVE-2020-11087)

    In FreeRDP less than or equal to 2.0.0, there is an out-of-bound read in ntlm_read_NegotiateMessage. This     has been fixed in 2.1.0. (CVE-2020-11088)

    In FreeRDP before 2.1.0, there is an out-of-bound read in irp functions (parallel_process_irp_create,     serial_process_irp_create, drive_process_irp_write, printer_process_irp_write, rdpei_recv_pdu,     serial_process_irp_write). This has been fixed in 2.1.0. (CVE-2020-11089)

    libfreerdp/gdi/gdi.c in FreeRDP > 1.0 through 2.0.0-rc4 has an Out-of-bounds Read. (CVE-2020-11522)

    libfreerdp/cache/bitmap.c in FreeRDP versions > 1.0 through 2.0.0-rc4 has an Out of bounds read.
    (CVE-2020-11525)

    libfreerdp/core/update.c in FreeRDP versions > 1.1 through 2.0.0-rc4 has an Out-of-bounds Read.
    (CVE-2020-11526)

    An issue was discovered in FreeRDP before 2.1.1. An out-of-bounds (OOB) read vulnerability has been     detected in ntlm_read_ChallengeMessage in winpr/libwinpr/sspi/NTLM/ntlm_message.c. (CVE-2020-13396)

    An issue was discovered in FreeRDP before 2.1.1. An out-of-bounds (OOB) read vulnerability has been     detected in security_fips_decrypt in libfreerdp/core/security.c due to an uninitialized value.

The remote NewStart CGSL host, running version MAIN 6.02, has freerdp packages installed that are affected by multiple vulnerabilities:

  - 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)

  - libfreerdp/core/update.c in FreeRDP versions > 1.1 through 2.0.0-rc4 has an Out-of-bounds Read.
    (CVE-2020-11526)

  - 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 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)

  - An issue was discovered in FreeRDP before 2.1.1. An out-of-bounds (OOB) read vulnerability has been     detected in ntlm_read_ChallengeMessage in winpr/libwinpr/sspi/NTLM/ntlm_message.c. (CVE-2020-13396)

  - An issue was discovered in FreeRDP before 2.1.1. An out-of-bounds (OOB) read vulnerability has been     detected in security_fips_decrypt in libfreerdp/core/security.c due to an uninitialized value.
    (CVE-2020-13397)

  - 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.
    This has been fixed in 2.1.0. (CVE-2020-11087)

  - In FreeRDP less than or equal to 2.0.0, there is an out-of-bound read in ntlm_read_NegotiateMessage. This     has been fixed in 2.1.0. (CVE-2020-11088)

  - In FreeRDP before 2.1.0, there is an out-of-bound read in irp functions (parallel_process_irp_create,     serial_process_irp_create, drive_process_irp_write, printer_process_irp_write, rdpei_recv_pdu,     serial_process_irp_write). This has been fixed in 2.1.0. (CVE-2020-11089)

  - 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 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)

  - libfreerdp/gdi/gdi.c in FreeRDP > 1.0 through 2.0.0-rc4 has an Out-of-bounds Read. (CVE-2020-11522)

  - libfreerdp/cache/bitmap.c in FreeRDP versions > 1.0 through 2.0.0-rc4 has an Out of bounds read.
    (CVE-2020-11525)

    (CVE-2020-13397)

  - 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.
    This has been fixed in 2.1.0. (CVE-2020-11087)

  - In FreeRDP less than or equal to 2.0.0, there is an out-of-bound read in ntlm_read_NegotiateMessage. This     has been fixed in 2.1.0. (CVE-2020-11088)

  - In FreeRDP before 2.1.0, there is an out-of-bound read in irp functions (parallel_process_irp_create,     serial_process_irp_create, drive_process_irp_write, printer_process_irp_write, rdpei_recv_pdu,     serial_process_irp_write). This has been fixed in 2.1.0. (CVE-2020-11089)

  - 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, 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 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)

  - libfreerdp/gdi/gdi.c in FreeRDP > 1.0 through 2.0.0-rc4 has an Out-of-bounds Read. (CVE-2020-11522)

  - libfreerdp/cache/bitmap.c in FreeRDP versions > 1.0 through 2.0.0-rc4 has an Out of bounds read.
    (CVE-2020-11525)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

  - 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)
