Name of the Vulnerable Software and Affected Versions Adobe InCopy version 16.4 and earlier

Description The issue is related to an out-of-bounds write vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction, where a victim must open a malicious file. This allows an attacker to potentially execute arbitrary code using a specially crafted malicious file.

Recommendations For Adobe InCopy version 16.4 and earlier, update to a version later than 16.4 to resolve the issue. As a temporary workaround, consider avoiding the use of untrusted or malicious files to minimize the risk of exploitation. Restrict access to potentially vulnerable file types until a patch is available.
