CVE-2024-3094 Vulnerability and Linux Distro Impacts
April 1, 2024
It’s no surprise that security experts are always on alert.
The need to be vigilant in the field of cybersecurity has once again become evident, especially after a chain of vulnerabilities has been uncovered. The ‘CVE-2024-3094’ vulnerability has revealed the depth and complexity of the problems that exist in the information security community.
Microsoft’s discovery of suspicious and malicious actions in the liblzma and xz packages led to the discovery of a critical vulnerability, CVE-2024-3094, highlighting the critical importance of SBOM, application security and ASPM.
It caused concern in the Linux ecosystem.
Source of CVE-2024-3094 Vulnerability
CVE-2024-3094 vulnerability was discovered as a result of anomalous behavior of the liblzma library that a PostgreSQL developer noticed when implemented on Debian sid installations. These anomalies revealed that certain versions of the xz libraries contained malicious code, making CVE-2024-3094 a critical issue in Linux application security.
As mentioned in a comment received from the Fedora project, one of the perpetrators of the vulnerability had been in contact for weeks about the inclusion of the “xz 5.6.x” plugin in Fedora 40 and 41 because of its “excellent new features”. It turned out that the Valgrind issue was created by a backdoor that he himself had added. This meant that Fedora teams were racing through the night to solve the problem by breaking the forbidden zone. It was noted that this person had been closely involved with the xz project for two years, adding various binary test files, and with this level of sophistication, older versions of xz should also be considered suspicious.
Critical Liblzma Library Issue
CVE-2024-3094 is due to a malicious code injection specifically affecting the liblzma library.
CVE-2024-3094 is a backdoor vulnerability with a depth that surpasses even modern cybersecurity practices.
This can lead to unauthorized access to Linux systems, posing serious risks to security and integrity.
The extent to which the security architecture of Linux distributions can protect against such advanced threats has been called into question by this case.
