ZDI-CAN-8782: Foxit Studio Photo TIFF File Parsing Out-Of-Bounds Read Remote Code Execution Vulnerability
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit Studio Photo. 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 handling of TIFF 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 structure. An attacker can leverage this vulnerability to execute code in the context of the current process.

Frequently Asked Questions
What must an attacker do to exploit this issue?
The attacker must persuade a user to visit a malicious page or open a malicious TIFF file. Exploitation does not require privileges, but it does require user interaction.
What level of access could successful exploitation provide?
An attacker can execute arbitrary code in the context of the current Foxit Studio Photo process. The reported impact includes compromise of confidentiality, integrity, and availability.
Which file content should be treated as untrusted?
TIFF files from untrusted sources should be treated as potentially malicious, because the flaw is in TIFF parsing. Avoid opening unsolicited or unexpected TIFF files until the affected installation has been remediated.
