An integer conversion vulnerability exists in the SORBAx64.dll RecvPacket functionality of WellinTech KingHistorian 35.01.00.05. A specially crafted network packet can lead to a buffer overflow. An attacker can send a malicious packet to trigger this vulnerability.
The product uses a signed primitive and performs a cast to an unsigned primitive, which can produce an unexpected value if the value of the signed primitive can not be represented using an unsigned primitive.
When converting from one data type to another, such as long to integer, data can be omitted or translated in a way that produces unexpected values. If the resulting values are used in a sensitive context, then dangerous behaviors may occur.
