CVE-2023-42095

Estado: ModificadaBaja (3.3)—

Foxit PDF Reader AcroForm Out-Of-Bounds Read Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Foxit PDF Reader. 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 Annotation objects. 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. Was ZDI-CAN-21879.

La falla específica existe en el manejo de objetos de anotación. El problema se debe a la falta de una validación adecuada de los datos proporcionados por el usuario, lo que puede provocar una lectura más allá del final de un búfer asignado.
