CWE-416
Use After Free
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
CVE-2019-6776 (GCVE-0-2019-6776)
Vulnerability from cvelistv5 – Published: 2019-10-04 17:37 – Updated: 2024-08-04 20:31
VLAI
Summary
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PhantomPDF 9.5.0.20723. 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 removeField method when processing watermarks within AcroForms. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process. Was ZDI-CAN-8801.

CVE-2020-10690 (GCVE-0-2020-10690)
Vulnerability from cvelistv5 – Published: 2020-05-08 13:48 – Updated: 2024-08-04 11:06
VLAI
Summary
There is a use-after-free in kernel versions before 5.5 due to a race condition between the release of ptp_clock and cdev while resource deallocation. When a (high privileged) process allocates a ptp device file (like /dev/ptpX) and voluntarily goes to sleep. During this time if the underlying device is removed, it can cause an exploitable condition as the process wakes up to terminate and clean all attached files. The system crashes due to the cdev structure being invalid (as already freed) which is pointed to by the inode.

CVE-2020-10899 (GCVE-0-2020-10899)
Vulnerability from cvelistv5 – Published: 2020-04-22 20:50 – Updated: 2024-08-04 11:14
VLAI
Summary
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit Reader 9.7.1.29511. 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 processing of XFA templates. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-10132.

CVE-2020-10900 (GCVE-0-2020-10900)
Vulnerability from cvelistv5 – Published: 2020-04-22 20:51 – Updated: 2024-08-04 11:14
VLAI
Summary
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit Reader 9.7.1.29511. 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 processing of AcroForms. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-10142.

Mitigation
Phase: Architecture and Design
Strategy: Language Selection
Description:
- Choose a language that provides automatic memory management.
Mitigation
Phase: Implementation
Strategy: Attack Surface Reduction
Description:
- When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.
