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

Weakness

The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.

Affected Software

Name Vendor Start Version End Version
Rdesktop Rdesktop * 1.8.3 (including)
