## Technical details

A heap-based buffer overflow vulnerability (CWE-122) exists in Adobe Bridge versions 15.1.5, 16.0.3, and earlier. The flaw is triggered when the application improperly handles memory allocation while processing a specially crafted file. An attacker can exploit this by convincing a victim to open a malicious file, leading to arbitrary code execution in the context of the current user. The issue has been addressed in versions 15.1.6 and 16.0.4.
