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

  - 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)

  - FreeRDP FreeRDP 2.0.0-rc3 released version before     commit 205c612820dac644d665b5bb1cdf437dc5ca01e3     contains a Other/Unknown vulnerability in     channels/drdynvc/client/drdynvc_main.c,     drdynvc_process_capability_request that can result in     The RDP server can read the client's memory.. This     attack appear to be exploitable via RDPClient must     connect the rdp server with echo option. This     vulnerability appears to have been fixed in after     commit     205c612820dac644d665b5bb1cdf437dc5ca01e3.(CVE-2018-1000     852)

  - 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)

  - Multiple integer overflows in client/X11/xf_graphics.c     in FreeRDP allow remote attackers to have an     unspecified impact via the width and height to the (1)     xf_Pointer_New or (2) xf_Bitmap_Decompress function,     which causes an incorrect amount of memory to be     allocated.(CVE-2014-0250)

  - Integer overflow in the license_read_scope_list     function in libfreerdp/core/license.c in FreeRDP     through 1.0.2 allows remote RDP servers to cause a     denial of service (application crash) or possibly have     unspecified other impact via a large ScopeCount value     in a Scope List in a Server License Request     packet.(CVE-2014-0791)

  - An exploitable code execution vulnerability exists in     the RDP receive functionality of FreeRDP     2.0.0-beta1+android11. A specially crafted server     response can cause an out-of-bounds write resulting in     an exploitable condition. An attacker can compromise     the server or use a man in the middle to trigger this     vulnerability.(CVE-2017-2835)

  - An exploitable denial of service vulnerability exists     within the reading of proprietary server certificates     in FreeRDP 2.0.0-beta1+android11. A specially crafted     challenge packet can cause the program termination     leading to a denial of service condition. An attacker     can compromise the server or use man in the middle to     trigger this vulnerability.(CVE-2017-2836)

  - An exploitable denial of service vulnerability exists     within the handling of security data in FreeRDP     2.0.0-beta1+android11. A specially crafted challenge     packet can cause the program termination leading to a     denial of service condition. An attacker can compromise     the server or use man in the middle to trigger this     vulnerability.(CVE-2017-2837)

  - An exploitable denial of service vulnerability exists     within the handling of challenge packets in FreeRDP     2.0.0-beta1+android11. A specially crafted challenge     packet can cause the program termination leading to a     denial of service condition. An attacker can compromise     the server or use man in the middle to trigger this     vulnerability.(CVE-2017-2838)

  - An exploitable denial of service vulnerability exists     within the handling of challenge packets in FreeRDP     2.0.0-beta1+android11. A specially crafted challenge     packet can cause the program termination leading to a     denial of service condition. An attacker can compromise     the server or use man in the middle to trigger this     vulnerability.(CVE-2017-2839)

client/X11: support for rail (remote app) icons was added

The licensing code was re-worked: Per-device licenses are now saved on the client and used on re-connect: WARNING: this is a change in FreeRDP behavior regarding licensing. If the old behavior is required, or no licenses should be saved use the new command line option +old-license (gh#/FreeRDP/FreeRDP#4979)

Improved order handling - only orders that were enable during capability exchange are accepted. WARNING and NOTE: some servers do improperly send orders that weren't negotiated, for such cases the new command line option /relax-order-checks was added to disable the strict order checking. If connecting to xrdp the options /relax-order-checks

*and* +glyph-cache are required. (gh#/FreeRDP/FreeRDP#4926)

Fixed automount issues

Fixed several audio and microphone related issues

Fixed X11 Right-Ctrl ungrab feature

Fixed race condition in rdpsnd channel server.

Disabled SSE2 for ARM and powerpc
