Heap-based buffer overflow in Microsoft Office PowerPoint allows an unauthorized attacker to execute code over a network.

A heap-based buffer overflow occurs when a program writes more data to a heap memory block than it can hold, potentially corrupting memory. This flaw allows an unauthorized attacker to execute arbitrary code remotely over a network by sending crafted input. The attack does not require prior authentication.

A use-after-free issue exists in Microsoft Edge (Chromium-based). This flaw allows an authorized attacker to execute arbitrary code over a network. Use-after-free is a memory corruption flaw that occurs when an application continues to use a pointer after it has been freed, which can be exploited to redirect program execution.
