Name of the Vulnerable Software and Affected Versions Foxit Reader version 9.7.0.29455

Description This issue allows remote attackers to disclose sensitive information 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 processing of JPEG2000 files due to the lack of proper validation of user-supplied data, resulting in a read past the end of an allocated buffer. An attacker can leverage this, in conjunction with other issues, to execute code in the context of the current process.

Recommendations For Foxit Reader version 9.7.0.29455, consider disabling the processing of JPEG2000 files as a temporary workaround until a patch is available. Restrict access to malicious pages or files to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
