Name of the Vulnerable Software and Affected Versions Adobe InDesign versions 16.0 and earlier

Description The issue is related to an out-of-bounds write vulnerability in Adobe InDesign, which can be exploited by a remote attacker to execute arbitrary code in the context of the current user. This can be achieved by parsing a specially crafted file, and it requires user interaction, such as opening a malicious file.

Recommendations For Adobe InDesign versions 16.0 and earlier, update to a version that contains a fix for this issue to prevent remote code execution. As a temporary workaround, consider avoiding the use of PCX file parsing until a patch is available. Restrict access to untrusted files to minimize the risk of exploitation.
