Name of the Vulnerable Software and Affected Versions Foxit Studio Photo version 3.6.6.931

Description This issue allows remote attackers to execute arbitrary code on affected installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The flaw exists within the handling of PSP files due to the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this to execute code in the context of the current process.

Recommendations For Foxit Studio Photo version 3.6.6.931, consider disabling the handling of PSP files until a patch is available to prevent exploitation. Restrict access to potentially malicious pages or files to minimize the risk of remote code execution. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
