freerdp-2.1.1-1.el8, vinagre-3.22.0-23.el8

FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. The xfreerdp client can connect to RDP servers such as Microsoft Windows machines, xrdp, and VirtualBox.

The vinagre packages provide the Vinagre remote desktop viewer for the GNOME desktop.

The following packages have been upgraded to a later upstream version: freerdp (2.1.1).

CVE-2020-11018
In FreeRDP less than or equal to 2.0.0, a possible resource exhaustion vulnerability can be performed. Malicious clients could trigger out of bound reads causing memory allocation with random size. This has been fixed in 2.1.0.
CVE-2020-11019
In FreeRDP less than or equal to 2.0.0, when running with logger set to "WLOG_TRACE", a possible crash of application could occur due to a read of an invalid array index. Data could be printed as string to local terminal. This has been fixed in 2.1.0.
CVE-2020-11038
In FreeRDP less than or equal to 2.0.0, an Integer Overflow to Buffer Overflow exists. When using /video redirection, a manipulated server can instruct the client to allocate a buffer with a smaller size than requested due to an integer overflow in size calculation. With later messages, the server can manipulate the client to write data out of bound to the previously allocated buffer. This has been patched in 2.1.0.
CVE-2020-11039
In FreeRDP less than or equal to 2.0.0, when using a manipulated server with USB redirection enabled (nearly) arbitrary memory can be read and written due to integer overflows in length checks. This has been patched in 2.1.0.
CVE-2020-11040
In FreeRDP less than or equal to 2.0.0, there is an out-of-bound data read from memory in clear_decompress_subcode_rlex, visualized on screen as color. This has been patched in 2.1.0.
CVE-2020-11041
In FreeRDP less than or equal to 2.0.0, an outside controlled array index is used unchecked for data used as configuration for sound backend (alsa, oss, pulse, ...). The most likely outcome is a crash of the client instance followed by no or distorted sound or a session disconnect. If a user cannot upgrade to the patched version, a workaround is to disable sound for the session. This has been patched in 2.1.0.
CVE-2020-11042
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 store information for later retrieval. This has been patched in 2.0.0.
CVE-2020-11043
In FreeRDP less than or equal to 2.0.0, there is an out-of-bounds read in rfx_process_message_tileset. Invalid data fed to RFX decoder results in garbage on screen (as colors). This has been patched in 2.1.0.
CVE-2020-11044
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.
CVE-2020-11045
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-2020-11046
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.
CVE-2020-11047
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 result data. This has been patched in 2.0.0.
CVE-2020-11048
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.
CVE-2020-11049
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.
CVE-2020-11058
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 in 2.0.0.
CVE-2020-11085
In FreeRDP before 2.1.0, there is an out-of-bounds read in cliprdr_read_format_list. Clipboard format data read (by client or server) might read data out-of-bounds. This has been fixed in 2.1.0.
CVE-2020-11086
In FreeRDP less than or equal to 2.0.0, there is an out-of-bound read in ntlm_read_ntlm_v2_client_challenge that reads up to 28 bytes out-of-bound to an internal structure. This has been fixed in 2.1.0.
CVE-2020-11087
In FreeRDP less than or equal to 2.0.0, there is an out-of-bound read in ntlm_read_AuthenticateMessage. This has been fixed in 2.1.0.
CVE-2020-11088
In FreeRDP less than or equal to 2.0.0, there is an out-of-bound read in ntlm_read_NegotiateMessage. This has been fixed in 2.1.0.
CVE-2020-11089
In FreeRDP before 2.1.0, there is an out-of-bound read in irp functions (parallel_process_irp_create, serial_process_irp_create, drive_process_irp_write, printer_process_irp_write, rdpei_recv_pdu, serial_process_irp_write). This has been fixed in 2.1.0.
