Medium 5.5
Out-of-bounds Read in FreeRDP
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 stor…

Medium 5.5
Improper Restriction of Operations within the Bounds of a Memory Buffer in FreeRDP
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.
-
Medium 5.5
Out-of-bounds Read in FreeRDPrdp_read_share_control_header
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.

Low 2.2
Out-of-bounds Read in FreeRDP
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.

Low 2.2

Low 2.2
Improper Restriction of Operations within the Bounds of a Memory Buffer in FreeRDP
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 …
