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

  - In FreeRDP before version 2.1.2, an out of bound reads occurs resulting in accessing a memory location     that is outside of the boundaries of the static array PRIMARY_DRAWING_ORDER_FIELD_BYTES. This is fixed in     version 2.1.2. (CVE-2020-11095)

  - In FreeRDP before version 2.1.2, there is a global OOB read in update_read_cache_bitmap_v3_order. As a     workaround, one can disable bitmap cache with -bitmap-cache (default). This is fixed in version 2.1.2.
    (CVE-2020-11096)

  - In FreeRDP before version 2.1.2, an out of bounds read occurs resulting in accessing a memory location     that is outside of the boundaries of the static array PRIMARY_DRAWING_ORDER_FIELD_BYTES. This is fixed in     version 2.1.2. (CVE-2020-11097)

  - In FreeRDP before version 2.1.2, there is an out-of-bound read in glyph_cache_put. This affects all     FreeRDP clients with `+glyph-cache` option enabled This is fixed in version 2.1.2. (CVE-2020-11098)

  - In FreeRDP before version 2.1.2, there is an out of bounds read in     license_read_new_or_upgrade_license_packet. A manipulated license packet can lead to out of bound reads to     an internal buffer. This is fixed in version 2.1.2. (CVE-2020-11099)

  - In FreeRDP less than or equal to 2.1.2, an integer overflow exists due to missing input sanitation in     rdpegfx channel. All FreeRDP clients are affected. The input rectangles from the server are not checked     against local surface coordinates and blindly accepted. A malicious server can send data that will crash     the client later on (invalid length arguments to a `memcpy`) This has been fixed in 2.2.0. As a     workaround, stop using command line arguments /gfx, /gfx-h264 and /network:auto (CVE-2020-15103)

  - In FreeRDP before version 2.1.2, there is an out of bounds read in TrioParse. Logging might bypass string     length checks due to an integer overflow. This is fixed in version 2.1.2. (CVE-2020-4030)

  - In FreeRDP before version 2.1.2, there is an out of bounds read in RLEDECOMPRESS. All FreeRDP based     clients with sessions with color depth < 32 are affected. This is fixed in version 2.1.2. (CVE-2020-4033)
