"This update for freerdp fixes the following issues :

  - CVE-2013-4118: Added a NULL pointer check to fix a
    server crash (bsc#829013).

  - CVE-2014-0791: Integer overflow in the
    license_read_scope_list function in
    libfreerdp/core/license.c in FreeRDP allowed 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. (bsc#857491)

  - CVE-2014-0250: Multiple integer overflows in
    client/X11/xf_graphics.c in FreeRDP allowed 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. (bsc#880317)

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
