PEAK-System PCAN Windows device drivers and installer contain a variable-length receive-record copy vulnerability (CWE-130) in versions up to 5.1.2/5.1.2.1151 that can result from using an unchecked record count when copying to a caller-supplied output buffer; HMS Networks released a fix in version 5.1.4 and recommends upgrading.
