Description

From CVE.org

libmodbus v3.1.10 is vulnerable to Buffer Overflow via the modbus_write_bits function. This issue can be triggered when the function is fed with specially crafted input, which leads to out-of-bounds read and can potentially cause a crash or other unintended behaviors.

Statement

Red Hat Product Security has determined that this vulnerability does not affect any currently supported Red Hat product. This assessment may evolve based on further analysis and discovery. For more information about this vulnerability and the products it affects, please see the linked references.

Understanding the Weakness (CWE)

Confidentiality

Technical Impact: Read Memory

Confidentiality

Technical Impact: Bypass Protection Mechanism

By reading out-of-bounds memory, an attacker might be able to get secret values, such as memory addresses, which can bypass protection mechanisms such as ASLR in order to improve the reliability and likelihood of exploiting a separate weakness to achieve code execution instead of just denial of service.

Availability,Integrity

Technical Impact: DoS: Crash, Exit, or Restart

An attacker might be able to cause a crash or other denial of service by causing the product to read a memory location that is not allowed (such as a segmentation fault), or to cause other conditions in which the read operation returns more data than is expected.
