Adobe Audition, a popular audio editing platform used by professionals worldwide, has been found to contain an out-of-bounds read vulnerability in versions 23.6.9, 24.4.6, and earlier. This vulnerability could potentially lead to the disclosure of sensitive memory information and allow an attacker to bypass security measures such as Address Space Layout Randomization (ASLR).

Exploit Details

The vulnerability, known by its Common Vulnerabilities and Exposures (CVE) identifier, CVE-2024-49536, results from improper handling of a memory buffer when processing particular file formats. An attacker could craft a malicious file that, when opened by an unsuspecting user, triggers the out-of-bounds read vulnerability. This exploitation could result in the disclosure of sensitive memory and, in turn, allow an attacker to bypass ASLR.

Code Snippet

To better understand the vulnerability, here's a simplified C code snippet demonstrating an out-of-bounds read when opening a malicious file:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main(int argc, char *argv[]) {
    FILE *file;
    char buffer[256];
    int offset;

    if (argc < 2) {
        printf("Usage: %s <filename>\n", argv[]);
        exit(1);
    }

    file = fopen(argv[1], "rb");
    if (file == NULL) {
        printf("Error opening file!\n");
        exit(1);
    }

    fread(buffer, 1, 256, file);
    offset = *((int *) (buffer + 250)); // Unsafe offset read

    printf("Sensitive data: %x\n", *((int *) (buffer + offset)));

    fclose(file);
    return ;
}

This code snippet demonstrates the improper handling of a memory buffer when reading an input file. The fread function reads the input file's content into a buffer, while the offset value is extracted from the buffer. When the printf function then accesses the buffer at the offset, an attacker could exploit an out-of-bounds read to reveal sensitive memory.
