CVE-2018-12565 : What You Need to Know

A vulnerability was identified in Linaro LAVA prior to version 2018.5.post1, potentially leading to remote code execution due to improper handling of user data.

Understanding CVE-2018-12565

This CVE involves a security issue in Linaro LAVA that could allow an attacker to execute remote code by exploiting a specific parsing method.

What is CVE-2018-12565?

This CVE refers to a vulnerability in Linaro LAVA before version 2018.5.post1, where the incorrect use of yaml.load() instead of yaml.safe_load() when processing user data can create a risk of remote code execution.

The Impact of CVE-2018-12565

The vulnerability in Linaro LAVA could potentially enable malicious actors to execute arbitrary code remotely, posing a significant security risk to affected systems.

Technical Details of CVE-2018-12565

This section provides more in-depth technical insights into the CVE.

Vulnerability Description

The issue arises from the improper use of yaml.load() instead of the safer yaml.safe_load() method during the parsing of user data in Linaro LAVA, opening the door to remote code execution.

Affected Systems and Versions

Affected Systems: Linaro LAVA before version 2018.5.post1
Affected Versions: Not specified

Exploitation Mechanism
