Corruption on the heap can be very hard to detect. A heap corruption could lead to a crash in heap management primitives that are invoked by Many C++ programs involve a lot of dynamic memory allocation by new. Many C++ crashes can be attributed to not checking for memory allocation failure.

Oct 18, 2016 · Unfortunately the call stack is for the native stack and doesn't really tell us anything. It appears that you're overwriting memory and therefore the heap is getting corrupted. This can be caused by many possible things including misusing pointers or freeing memory that was never allocated.
Out of bounds memory access will very likely result in the corruption of relevant memory, and perhaps instructions, possibly leading to a crash. Heap-based buffer overflow in media player using a long entry in a playlist.
This implies prohibiting casting to pointers (and also prohibits C-style cast and static_cast<> with respect to pointers; however, implicit pointer casts and dynamic_cast<> are ok). Note that although casting from pointers won’t cause memory corruption, it is not a good idea in general.
Nov 11, 2016 · As for the general question, On windows I use microsoft application verifier and configure it to allocate non-accessible pages immediately before/after every allocation, which causes most out of bounds writes to immediately crash instead of silently causing memory corruption.
Ariele Caltabiano (kimiya) working with Trend Micro’s Zero Day Initiative (ZDI) has identified a heap memory corruption and two stack buffer overflow vulnerabilities in Fatek’s Automation PM and FV Designer applications. Fatek has not produced an update to mitigate these vulnerabilities. ZDI has coordinated with NCCIC/ICS-CERT.
Apr 25, 2016 · The correct procedure is to create the object from the HEAP (the new operator) and pass that pointer to the other thread. When that thread is finished with it, it deletes it with the delete operator. If the other thread needs to send the memory back that is modified, then it does not delete the memory pointer but sends the pointer back.
Apr 18, 2019 · When memory is allocated from the heap, the memory management functions need someplace to store information about the allocations. That place is the heap itself; this means that the heap is composed of alternating areas of memory that are used by the program and by the memory management functions themselves. Oct 14, 2013 · Here is sample call stack where you could suspect a heap memory corruption. In the above scenario the module calling calloc crashed as the heap is already corrupted. The next steps would be to enable libc memory debugging options to identify source of corruption. Memory leaks usually trigger Out of Memory Java exceptions or will result in OOM ...

Attack Surface Outside of the web browser, the typical use case for Java provides very little attack surface. The other Java invocation method is by way of Windows file associations. Heap metadata attacks have become one of the primary ways in which attackers exploit memory corruption vulnerabilities. While heap implementation developers have introduced mitigations to prevent and detect corruption, it is still possible for attackers to work around them. Session Module C Interface Query for the amount of heap memory used by a session object. sqlite3_int64 sqlite3session_memory_used(sqlite3_session *pSession); This API returns the total amount of heap memory in bytes currently used by the session object passed as the only argument.
