CVE-2012-4359: Sielcosistemi winlog pro improper input validation vulnerability

Sielcosistemi · Winlog Pro

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.
