To eliminate double-free vulnerabilities, it is necessary to guarantee that dynamic memory is freed exactly one time. Programmers should be wary when freeing memory in a loop or conditional statement; if coded incorrectly, these constructs can lead to double-free vulnerabilities. It is also a common error to misuse the {{realloc()}} function in a manner that results in double-free vulnerabilities (see \[[MEM04-A. Do not perform zero length allocations]\]). |
