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.

freerdp: Integer overflow in VIDEO channel
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.
Statement: Although this flaw affects versions of freerdp shipped with Red Hat Enterprise Linux 7 and 8, Red Hat Product Security views this flaw as having low impact because it only affects the freerdp client, the user must connect to an untrusted or compromised server, and it would not lead to a persistent denial of service if expl
