Analysis Summary

CVE-2021-42734 

This vulnerability allows remote attackers to disclose sensitive information on affected installations of Adobe Photoshop. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. 
The specific flaw exists within the parsing of TIF files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
