CVE-2021-31449 (GCVE-0-2021-31449)

Vulnerability from cvelistv5 – Published: 2021-05-07 20:16 – Updated: 2024-08-03 22:55
VLAI
Summary
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 U3D objects embedded in PDF files. The issue results from the lack of validating the existence of an object prior to performing further free operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-13280.

CVE-2021-34333 (GCVE-0-2021-34333)

Vulnerability from cvelistv5 – Published: 2021-07-13 11:03 – Updated: 2024-08-04 00:05
VLAI
Summary
A vulnerability has been identified in JT2Go (All versions < V13.2), Teamcenter Visualization (All versions < V13.2). The BMP_Loader.dll library in affected applications lacks proper validation of user-supplied data when parsing BMP files. A malformed input file could result in double free of an allocated buffer that leads to a crash. An attacker could leverage this vulnerability to cause denial of service condition. (CNVD-C-2021-79295)

CVE-2021-34734 (GCVE-0-2021-34734)

Vulnerability from cvelistv5 – Published: 2021-08-18 19:40 – Updated: 2024-11-07 22:03
VLAI
Title
Cisco Video Surveillance 7000 Series IP Cameras Link Layer Discovery Protocol Double-Free Denial of Service Vulnerability
Summary
A vulnerability in the Link Layer Discovery Protocol (LLDP) implementation for the Cisco Video Surveillance 7000 Series IP Cameras firmware could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition. This vulnerability is due to improper management of memory resources, referred to as a double free. An attacker could exploit this vulnerability by sending crafted LLDP packets to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. Note: LLDP is a Layer 2 protocol. To exploit these vulnerabilities, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent).

Title
Cisco IOS XE Software for Catalyst 9000 Family Wireless Controllers CAPWAP Denial of Service Vulnerabilities
Summary
Multiple vulnerabilities in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol processing of Cisco IOS XE Software for Cisco Catalyst 9000 Family Wireless Controllers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. These vulnerabilities are due to insufficient validation of CAPWAP packets. An attacker could exploit the vulnerabilities by sending a malformed CAPWAP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to crash and reload, resulting in a DoS condition.

CVE-2021-3492 (GCVE-0-2021-3492)

Vulnerability from cvelistv5 – Published: 2021-04-17 04:20 – Updated: 2024-09-17 03:54

Title
Ubuntu linux kernel shiftfs file system double free vulnerability
Summary
Shiftfs, an out-of-tree stacking file system included in Ubuntu Linux kernels, did not properly handle faults occurring during copy_from_user() correctly. These could lead to either a double-free situation or memory not being freed at all. An attacker could use this to cause a denial of service (kernel memory exhaustion) or gain privileges via executing arbitrary code. AKA ZDI-CAN-13562.
Severity
8.8 (High)

Title
Linux Kernel Bluetooth CMTP Module Double Free Privilege Escalation Vulnerability
Summary
Linux Kernel Bluetooth CMTP Module Double Free Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the CMTP module. The issue results from the lack of validating the existence of an object prior to performing further free operations on the object. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the kernel. Was ZDI-CAN-11977.

Mitigation

Phase: Architecture and Design

Description:

  • Choose a language that provides automatic memory management.
Mitigation

Phase: Implementation

Description:

  • Ensure that each allocation is freed only once. After freeing a chunk, set the pointer to NULL to ensure the pointer cannot be freed again. In complicated error conditions, be sure that clean-up routines respect the state of allocation properly. If the language is object oriented, ensure that object destructors delete each chunk of memory only once.
Mitigation

Phase: Implementation

Description:

  • Use a static analysis tool to find double free instances.
