DHCP Server Service Denial of Service Vulnerability
An exploitable integer underflow vulnerability exists in the mdnscap binary of the CUJO Smart Firewall, version 7003. When parsing SRV records in an mDNS packet, the "RDLENGTH" value is handled incorrectly, leading to an out-of-bounds access that crashes the mdnscap process. An unauthenticated attacker can send an mDNS message to trigger this vulnerability.
A CWE-191: Integer Underflow (Wrap or Wraparound) vulnerability exists that could cause a denial of service of the controller due to memory access violations when using the Modbus TCP protocol. Affected products: Modicon M340 CPU (part numbers BMXP34*)(V3.40 and prior), Modicon M580 CPU (part numbers BMEP* and BMEH*)(V3.22 and prior), Legacy Modicon Quantum/Premium(All Versions), Modicon Momentum MDI (171CBU*)(All Versions), Modicon MC80 (BMKC80)(V1.7 and prior)
Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.8, a specially crafted TCP stream can lead to a very large buffer overflow while being zero-filled during initialization with memset due to an unsigned integer underflow. The issue has been addressed in Suricata 7.0.8.
