Summary
InDesign Desktop versions 21.1, 20.5.1 and earlier are affected by an out-of-bounds read vulnerability that could lead to memory exposure. An attacker could leverage this vulnerability to disclose sensitive information stored in memory. Exploitation requires user interaction – the victim must open a malicious file.
Risk Assessment
The risk involves potential leakage of confidential data from application memory, which could expose the organization to loss of sensitive information. The attack requires the user to open a malicious file.
Recommendation
It is recommended to immediately update InDesign Desktop to the latest available version that includes the fix. Users should also be informed about the risks of opening files from untrusted sources.
