Technical details
Lightroom Classic is affected by an out-of-bounds write vulnerability in its file parsing logic. The vulnerability occurs when the application processes a malicious file without properly validating buffer boundaries, allowing an attacker to write arbitrary data beyond the intended memory region. Exploitation requires user interaction—a victim must open a malicious file—and results in arbitrary code execution in the context of the current user. No remote attack vector is available; the attacker must socially engineer the victim to open the file. Patches are available through Adobe's security updates.
