CWE-416 释放后使用 类漏洞列表 4332

CWE-416 释放后使用 类弱点 4332 条 CVE 漏洞汇总,含 AI 中文分析。

CWE-416 释放后使用是一种内存安全漏洞,指程序在释放内存后仍引用该内存区域。攻击者常利用此缺陷,通过重新分配内存并控制其内容,诱导程序执行恶意代码或读取敏感数据,从而引发远程代码执行或信息泄露。开发者应避免此类风险,确保在指针置空前彻底解除引用,采用智能指针等自动内存管理机制,并严格验证内存生命周期,防止悬空指针操作。

MITRE CWE 官方描述
CWE:CWE-416 Use After Free 英文:产品在内存被释放后重新使用或引用该内存。在此之后,该内存可能会被重新分配并保存到另一个指针中,而原始指针则指向新分配内存中的某个位置。由于内存“属于”操作新指针的代码,因此使用原始指针的任何操作均不再有效。
常见影响 (4)
Integrity Modify Memory
The use of previously freed memory may corrupt valid data, if the memory area in question has been allocated and used properly elsewhere.
Availability DoS: Crash, Exit, or Restart
If chunk consolidation occurs after the use of previously freed data, the process may crash when invalid data is used as chunk information.
Confidentiality Read Memory
Read operations on freed memory can sometimes leak sensitive information instead of causing a crash
Integrity, Confidentiality, Availability Execute Unauthorized Code or Commands
If malicious data is entered before chunk consolidation can take place, it may be possible to take advantage of a write-what-where primitive to execute arbitrary code. If the newly allocated data happens to hold a class, in C++ for example, various function pointers may be scattered within the heap …
缓解措施 (2)
Architecture and Design Choose a language that provides automatic memory management.
Implementation When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.
Effectiveness: Defense in Depth
代码示例 (2)
The following example demonstrates the weakness.
#include <stdio.h> #include <unistd.h> #define BUFSIZER1 512 #define BUFSIZER2 ((BUFSIZER1/2) - 8) int main(int argc, char **argv) { char *buf1R1; char *buf2R1; char *buf2R2; char *buf3R2; buf1R1 = (char *) malloc(BUFSIZER1); buf2R1 = (char *) malloc(BUFSIZER1); free(buf2R1); buf2R2 = (char *) malloc(BUFSIZER2); buf3R2 = (char *) malloc(BUFSIZER2); strncpy(buf2R1, argv[1], BUFSIZER1-1); free(buf1R1); free(buf2R2); free(buf3R2); }
Bad · C
The following code illustrates a use after free error:
char* ptr = (char*)malloc (SIZE); if (err) { abrt = 1; free(ptr); } ... if (abrt) { logError("operation aborted before commit", ptr); }
