Vulnerability from cvelistv5 – Published: 2023-03-29 00:00 – Updated: 2025-02-18 16:58
VLAI
Summary
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Bentley View 10.16.02.022. 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 3DM files. The issue results from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-16282.

CVE-2022-2308 (GCVE-0-2022-2308)

Vulnerability from cvelistv5 – Published: 2022-09-01 20:01 – Updated: 2024-08-03 00:32
VLAI
Summary
A flaw was found in vDPA with VDUSE backend. There are currently no checks in VDUSE kernel driver to ensure the size of the device config space is in line with the features advertised by the VDUSE userspace application. In case of a mismatch, Virtio drivers config read helpers do not initialize the memory indirectly passed to vduse_vdpa_get_config() returning uninitialized memory from the stack. This could cause undefined behavior or data leaks in Virtio drivers.
Severity
No CVSS data available.

CVE-2021-46631 (GCVE-0-2021-46631)

Vulnerability from cvelistv5 – Published: 2022-02-18 19:46 – Updated: 2024-08-04 05:10
VLAI
Summary
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Bentley View 10.15.0.75. 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 TIF images. The issue results from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-15461.

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 JT files. The issue results from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. Was ZDI-CAN-15364."

Mitigation MIT-57
Implementation

Strategy: Attack Surface Reduction

Ensure that critical variables are initialized before first use [REF-1485].

Mitigation
Build and Compilation

Strategy: Compilation or Build Hardening

Most compilers will complain about the use of uninitialized variables if warnings are turned on.

Mitigation
Implementation Operation

When using a language that does not require explicit declaration of variables, run or compile the software in a mode that reports undeclared or unknown variables. This may indicate the presence of a typographic error in the variable's name.

Mitigation
Requirements

Strategy: Language Selection

Choose a language that is not susceptible to these issues.

Mitigation
Architecture and Design

Mitigating technologies such as safe string libraries and container abstractions could be introduced.
