In the Java programming language, heap pollution is a situation that arises when a variable of a parameterized type refers to an object that is not of that parameterized type. [1] This situation is normally detected during compilation and indicated with an unchecked warning. [1] Later, during runtime heap pollution will often cause a ClassCast ...
A heap overflow, heap overrun, or heap smashing is a type of buffer overflow that occurs in the heap data area. Heap overflows are exploitable in a different manner to that of stack-based overflows. Memory on the heap is dynamically allocated at runtime and typically contains program data.
A mergeable heap supports the usual heap operations: [1] Make-Heap(), create an empty heap. Insert(H,x), insert an element x into the heap H. Min(H), return the minimum element, or Nil if no such element exists. Extract-Min(H), extract and return the minimum element, or Nil if no such element exists. And one more that distinguishes it: [1]
The popularity of the Java programming language has made escape analysis a target of interest. Java's combination of heap-only object allocation, built-in threading, the Sun HotSpot dynamic compiler, and OpenJ9 's just-in-time compiler (JIT) creates a candidate platform for escape analysis related optimizations (see Escape analysis in Java ).
The last day to apply for the regular HEAP benefit is May 31. For more information on the programs, visit energyhelp.ohio.gov or to schedule your winter crisis appointment with HARCATUS, call 855 ...
The part of the source code of an exploit that implements this technique is called a heap spray. [1] In general, code that sprays the heap attempts to put a certain sequence of bytes at a predetermined location in the memory of a target process by having it allocate (large) blocks on the process's heap and fill the bytes in these blocks with ...
From January 2008 to December 2012, if you bought shares in companies when Douglas N. Daft joined the board, and sold them when he left, you would have a 43.9 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
Illustration of the table-heap compaction algorithm. Objects that the marking phase has determined to be reachable (live) are colored, free space is blank. A table-based algorithm was first described by Haddon and Waite in 1967. [1] It preserves the relative placement of the live objects in the heap, and requires only a constant amount of overhead.
