Sielco Sistemi Winlog Pro SCADA before 2.07.18 and Winlog Lite SCADA before 2.07.18 do not validate the return value of the realloc function, which allows remote attackers to cause a denial of service (invalid 0x00 write operation and daemon crash) or possibly have unspecified other impact via a port-46824 TCP packet with a crafted negative integer after the opcode. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-4358.
