medium Nessus Plugin ID 146738


The remote EulerOS host is missing multiple security updates.


According to the versions of the freerdp packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- 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 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)

- libfreerdp/gdi/region.c in FreeRDP versions > 1.0 through 2.0.0-rc4 has an Integer Overflow.(CVE-2020-11523)
