Mike Jumper created GUACAMOLE-2074:
--------------------------------------
Summary: Disagreement in signedness causes assertion failures with
FreeRDP 3.x
Key: GUACAMOLE-2074
URL: https://issues.apache.org/jira/browse/GUACAMOLE-2074
Project: Guacamole
Issue Type: Bug
Components: RDP
Reporter: Mike Jumper
In some parts of Guacamole's RDPDR support, signed integers are used to store
values that actually should be unsigned. In the case of RDPDR status codes,
those values are large enough that they become negative and fail sanity checks
when written to the RDP PDU with FreeRDP 3.x:
{code:none}
Assertion failed: (((status) >= 0)) (channels/rdpdr/rdpdr.c:
guac_rdpdr_new_io_completion: 137)
{code}
This did not fail previously as FreeRDP 2.x simply wrote the values in binary
form, effectively ignoring signedness.
