Name of the Vulnerable Software and Affected Versions Foxit PDF Reader (affected versions not specified) Foxit PDF Editor (affected versions not specified)

Description The issue is related to a buffer data out-of-bounds read in Foxit PDF Reader and Foxit PDF Editor. It 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 signature fields, resulting from the lack of proper validation of user-supplied data, which can lead to a read past the end of an allocated buffer.

Recommendations For Foxit PDF Reader, consider disabling the handling of signature fields until a patch is available. For Foxit PDF Editor, restrict access to the AcroForm signature feature to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
