The consequences of this kind of internal application state corruption can be various - from no consequences, if the calling application does not depend on the contents of non-volatile XMM registers at all, to the worst consequences, where the attacker could get complete control of the application process. The vulnerable code is used only on newer x86_64 processors supporting the AVX512-IFMA instructions. Before returning to the caller all the XMM registers are set to zero rather than restoring their previous content. The POLY1305 MAC (message authentication code) implementation in OpenSSL does not save the contents of non-volatile XMM registers on Windows 64 platform when calculating the MAC of data larger than 64 bytes. Impact summary: If in an application that uses the OpenSSL library an attacker can influence whether the POLY1305 MAC algorithm is used, the application state might be corrupted with various application dependent consequences. Download from summary: The POLY1305 MAC (message authentication code) implementation contains a bug that might corrupt the internal state of applications on the Windows 64 platform when running on newer X86_64 processors supporting the AVX512-IFMA instructions. Features: shows what is connected to every switch port in a simple table format pulls ARP table from a router to display IP information of connected clients scans the current subnet for MAC-to-IP address mappings if there is no router comes in two editions: a GUI application and a console application for using in scripts allows direct launch of other applications and tools for convenience and easy management fully supports SNMPv1, SNMPv2c and SNMPv3, including bulk operations available for Windows, macOS and Linux. A great tool for troubleshooting network connectivity issues. Additionally, it can display each client's network card vendor, port speed, and the counters of erroneous and discarded frames for every port. For every connected port, it lists the MAC address, IP address and host names of the computers associated with that port. SoftPerfect Switch Port Mapper works with managed network switches and reports what is connected to switch ports, and which ports are not connected.
