How the CVE Works
CVE-2025-43558 is an out-of-bounds write vulnerability in Adobe InDesign (versions ID20.2, ID19.5.3, and earlier). When a user opens a maliciously crafted file, the software fails to properly validate memory boundaries, allowing an attacker to write data beyond the allocated buffer. This can lead to arbitrary code execution under the current user’s privileges. Exploitation requires user interaction, as the victim must open the malicious file. The flaw stems from improper bounds checking during file parsing, enabling attackers to manipulate memory and potentially hijack control flow.
