CWE-191 整数下溢(超界折返) 类漏洞列表 307

CWE-191 整数下溢(超界折返) 类弱点 307 条 CVE 漏洞汇总,含 AI 中文分析。

CWE-191 整数下溢漏洞发生于程序执行减法操作时,结果低于整数类型允许的最小值,导致数值回绕至最大值附近,产生非预期结果。攻击者常利用此缺陷绕过安全检查或引发逻辑错误,进而可能导致缓冲区溢出等更严重的安全问题。开发者应通过添加边界检查、使用更大范围的整数类型或启用编译器的溢出检测功能,确保算术运算在合法范围内,从而有效防止此类漏洞发生。

MITRE CWE 官方描述
CWE:CWE-191 整数下溢(Integer Underflow)(回绕或回绕现象 Wrap or Wraparound) 产品从一个值中减去另一个值,导致结果小于允许的最小整数值,从而产生一个不等于正确结果的值。 这种情况可能发生在有符号(signed)和无符号(unsigned)情形中。
常见影响 (3)
Availability DoS: Crash, Exit, or Restart, DoS: Resource Consumption (CPU), DoS: Resource Consumption (Memory), DoS: Instability
This weakness will generally lead to undefined behavior and therefore crashes. In the case of overflows involving loop index variables, the likelihood of infinite loops is also high.
Integrity Modify Memory
If the value in question is important to data (as opposed to flow), simple data corruption has occurred. Also, if the wrap around results in other conditions such as buffer overflows, further memory corruption may occur.
Confidentiality, Availability, Access Control Execute Unauthorized Code or Commands, Bypass Protection Mechanism
This weakness can sometimes trigger buffer overflows which can be used to execute arbitrary code. This is usually outside the scope of a program's implicit security policy.
代码示例 (2)
The following example subtracts from a 32 bit signed integer.
#include <stdio.h> #include <stdbool.h> main (void) { int i; i = -2147483648; i = i - 1; return 0; }
Bad · C
This code performs a stack allocation based on a length calculation.
int a = 5, b = 6; size_t len = a - b; char buf[len];    // Just blows up the stack }
