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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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-2018-0170 (GCVE-0-2018-0170)
Vulnerability from cvelistv5 – Published: 2018-03-28 22:00 – Updated: 2024-12-02 20:53
VLAI
Summary
A vulnerability in the Cisco Umbrella Integration feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition, related to the OpenDNS software. The vulnerability is due to a logic error that exists when handling a malformed incoming packet, leading to access to an internal data structure after it has been freed. An attacker could exploit this vulnerability by sending crafted, malformed IP packets to an affected device. A successful exploit could allow the attacker to cause an affected device to reload, resulting in a DoS condition. Cisco Bug IDs: CSCvb86327.

CVE-2018-10496 (GCVE-0-2018-10496)
Vulnerability from cvelistv5 – Published: 2018-09-24 23:00 – Updated: 2024-08-05 07:39
VLAI
Summary
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Samsung Internet Browser Fixed in version 6.4.0.15. 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 TypedArray objects. 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 under the context of the current process. Was ZDI-CAN-5326.

CVE-2018-11617 (GCVE-0-2018-11617)
Vulnerability from cvelistv5 – Published: 2018-07-31 20:00 – Updated: 2024-08-05 08:17
VLAI
Summary
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Foxit Reader 9.0.0.29935. 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 Format events for ComboBox fields. 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 under the context of the current process. Was ZDI-CAN-5415.
Severity
No CVSS data available.

CVE-2018-1166 (GCVE-0-2018-1166)
Vulnerability from cvelistv5 – Published: 2018-02-21 14:00 – Updated: 2024-08-05 03:51
VLAI
Summary
This vulnerability allows local attackers to escalate privileges on vulnerable installations of Joyent SmartOS release-20170803-20170803T064301Z. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the SMBIOC_TREE_RELE ioctl. 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 under the context of the host OS. Was ZDI-CAN-4984.

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.
