## Technical details

An out-of-bounds write vulnerability (CWE-787) exists in Adobe Bridge versions 15.1.5, 16.0.3, and earlier. The flaw occurs when the application processes a specially crafted file, leading to memory corruption. An attacker can leverage this to execute arbitrary code with the privileges of the current user. This is a local attack vector that requires user interaction, specifically the opening of a malicious file. Adobe has released patches in versions 15.1.6 and 16.0.4 to address this issue.
