Vulnerabilities 19
-
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 FreeRDP
In FreeRDP after 1.1 and before 2.0.0, there is an out-of-bounds read in autodetect_recv_bandwidth_measure_results. A malicious server can extract up to 8 bytes of client memory with a manipulated message by providing a short input and reading the measurement…
-
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
Double Free in FreeRDP
In FreeRDP greater than 1.2 and before 2.0.0, a double free in update_read_cache_bitmap_v3_order crashes the client application if corrupted data from a manipulated server is parsed. 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
Out-of-bounds Read in FreeRDPrdp_read_flow_control_pdu
In FreeRDP after 1.0 and before 2.0.0, there is an out-of-bounds read. It only allows to abort a session. No data extraction is possible. This has been fixed in 2.0.0.
-
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 …
