This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PDF Reader 11.1.0.52543. 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 parsing of JPEG2000 images. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated structure. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-15811.
Foxit PDF Reader before 11.2.1 and Foxit PDF Editor before 11.2.1 have a Stack-Based Buffer Overflow related to XFA, for the 'subform colSpan="-2"' and 'draw colSpan="1"' substrings.
A memory corruption vulnerability exists in the JavaScript engine of Foxit Software’s PDF Reader, version 11.1.0.52543. A specially-crafted PDF document can trigger an exception which is improperly handled, leaving the engine in an invalid state, which can lead to memory corruption and arbitrary code execution. An attacker needs to trick the user to open the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially-crafted, malicious site if the browser plugin extension is enabled.
A use-after-free vulnerability exists in the JavaScript engine of Foxit Software’s PDF Reader, version 11.1.0.52543. A specially-crafted PDF document can trigger the reuse of previously freed memory, which can lead to arbitrary code execution. An attacker needs to trick the user to open the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially-crafted, malicious site if the browser plugin extension is enabled.
An issue was discovered in Foxit PDF Reader before 11.0.1 and PDF Editor before 11.0.1. It mishandles situations in which an array size (derived from a /Size entry) is smaller than the maximum indirect object number, and thus there is an attempted incorrect array access (leading to a NULL pointer dereference, or out-of-bounds read or write).
An issue was discovered in Foxit PDF Editor before 11.0.1 and PDF Reader before 11.0.1 on macOS. It mishandles missing dictionary entries, leading to a NULL pointer dereference, aka CNVD-C-2021-95204.
