CVE-2021-31454

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit Reader 10.1.1.37576. 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 the Decimal element. A crafted leadDigits value in a Decimal element can trigger an overflow of a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute arbitrary code in the context of the current process. Was ZDI-CAN-13095.
