首先要分析的函数是heapBuffer,其主要作用是提供一个简单的API来创建基于 JVM 堆内存的HeapBuffer对象,并确保参数符合要求,源码如下所示: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 staticfinal intDEFAULT_MAX_CAPACITY=Integer.MAX_VALUE;@OverridepublicByteBufheapBuffer(int initialCapacity){returnheapBuffe...
HeapBuffer通常由一个内存池(Memory Pool)和一个内存分配器(Memory Allocator)组成,用于管理内存的分配和回收。 二、HeapBuffer创建过程 HeapBuffer的创建过程主要包括以下几个步骤: 内存池初始化 在创建HeapBuffer之前,首先需要初始化一个内存池。内存池是一个预先分配好的连续内存区域,用于存储HeapBuffer所管理的对象。
poc0 is a malformed zip file generated by fuzzer. I used the "-x" flag when testing and it came into a heap-buffer-overflow crash. So maybe you could give a proper prompt when using "-x" to extract malformed files like poc0? Aaaah, ok. When built without ASAN thepoc0zipfile trigg...
返回字符串时出现运行时错误"heap-buffer-overflow" 编译代码时,我收到一个heap-buffer-overflow错误: char * reverseWords(char * s){ int n = strlen(s); char *res = malloc(n + 1); strcpy(res,s); char temp[100]; int i = 0; int j = 0;...
Describe: A heap-buffer-overflow was discovered in zziplib v0.13.77. The issue is being triggered in function __zzip_parse_root_directory() at zzip/zip.c:539.Attackers may exploit this vulnerability to execute and cause a DOS attack. Rep...
1、 劣势:创建和释放Direct Buffer的代价比Heap Buffer得要高。 2、 差别:Direct Buffer不是分配在堆上的,它不被GC直接管理(但Direct Buffer的JAVA对象是归GC管理的,只要GC回收了它的JAVA对象。操作系统才会释放Direct Buffer所申请的空间)。它似乎给人感觉是“内核缓冲区(buffer in kernel)”。Heap Buffer则是分...

java NIO - DirectBuffer 和 HeapBuffer 问题:DirectBuffer 属于堆外存,那应该还是属于用户内存,而不是内核内存? FileChannel 的read(ByteBuffer dst)函数,write(ByteBuffer src)函数中,如果传入的参数是HeapBuffer类型,则会临时申请一块DirectBuffer,进行数据拷贝,而不是直接进行数据传输,这是出于什么原因?
