Mike Jumper updated GUACAMOLE-2074:
-----------------------------------
Affects Version/s: 1.6.0
> 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
> Affects Versions: 1.6.0
> Reporter: Mike Jumper
> Priority: Blocker
>
> 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.
