Affected versions of FreeRDP are missing a range check for input offset
index in ZGFX decoder. A malicious server can trick a FreeRDP based client
to read out of bound data and try to decode it. (CVE-2022-39317)

Affected versions of FreeRDP are missing input validation in 'urbdrc'
channel. A malicious server can trick a FreeRDP based client to crash with
division by zero. (CVE-2022-39318)

Affected versions of FreeRDP are missing input length validation in the
'urbdrc' channel. A malicious server can trick a FreeRDP based client to
read out of bound data and send it back to the server. (CVE-2022-39319)

Affected versions of FreeRDP may attempt integer addition on too narrow
types leads to allocation of a buffer too small holding the data written.
A malicious server can trick a FreeRDP based client to read out of bound
data and send it back to the server. (CVE-2022-39320)

Affected versions of FreeRDP are missing path canonicalization and base
path check for `drive` channel. A malicious server can trick a FreeRDP
based client to read files outside the shared directory. (CVE-2022-39347)");
