rdesktop versions up to and including v1.8.3 contain an Integer Underflow that leads to a Heap-Based Buffer Overflow in the function rdpsnddbg_process() and results in memory corruption and probably even a remote code execution.

Security readout for executives and security teams

CVE-2018-20180 affects rdesktop clients up to v1.8.3. A malicious or compromised RDP server may be able to corrupt the client’s memory and possibly run code on the user’s machine. The practical risk is highest where staff or administrators use rdesktop to connect to untrusted or externally managed RDP systems. Exposure is limited to environments running rdesktop v1.8.3 or earlier, especially Linux/Unix workstations, jump hosts, or admin systems using rdesktop for RDP access. Systems using other RDP clients are not identified as affected in the provided sources. Treat as a targeted admin-workstation risk. Prioritize patching or removing old rdesktop on systems used by IT, support, and security teams, because compromise of those clients may have outsized operational impact. Mitigation focus: Inventory systems for rdesktop v1.8.3 or earlier.; Apply the upstream fix or distribution security updates from Debian, Gentoo, or openSUSE.; Restrict rdesktop use to trusted RDP servers until patched..
