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.

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-2021-21797 (GCVE-0-2021-21797)

Vulnerability from cvelistv5 – Published: 2021-10-18 12:45 – Updated: 2024-08-03 18:23
VLAI
Summary
An exploitable double-free vulnerability exists in the JavaScript implementation of Nitro Pro PDF. A specially crafted document can cause a reference to a timeout object to be stored in two different places. When closed, the document will result in the reference being released twice. This can lead to code execution under the context of the application. An attacker can convince a user to open a document to trigger this vulnerability.

Mitigation
Architecture and Design

Choose a language that provides automatic memory management.

Mitigation
Implementation

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
Implementation

Use a static analysis tool to find double free instances.
