In the xfig diagramming tool, a stack overflow while running fig2dev allows memory corruption via local input manipulation through the read_objects function. This vulnerability impacts both the Fig2dev component and the RedHat enterprise_linux, making it significant for organizations using these products.
The severity of this vulnerability is classified as medium, with a CVSS score of 5.5. The implications for organizations can be substantial, as it affects data integrity, potentially leading to unauthorized modifications of data.
Currently, there are no known exploits associated with this vulnerability, and it has not yet reached high-profile status. However, organizations should prioritize remediation to mitigate any risks associated with memory corruption that may arise from local input manipulation.
Organizations should address this vulnerability in their patch cycle, as delaying remediation could expose them to unnecessary risks.
Vulnerability Details
The vulnerability is identified as CVE-2025-46398, affecting the Fig2dev tool (version 3.2.9a) and various versions of RedHat's enterprise_linux (6.0, 7.0, and 8.0). It was published on April 23, 2025, and is classified under CWE-121.
The CVSS vector indicates that the attack vector is local, with low complexity and low privileges required. User interaction is not needed, which makes it easier for an attacker to exploit the vulnerability.
Technical Analysis
The root cause of the vulnerability lies in the handling of local input within the read_objects function of the Fig2dev tool, which can lead to a stack overflow. Attackers may leverage this flaw to manipulate memory, potentially leading to data corruption.
The attack vector is local, meaning an attacker must have access to the target system. The attack complexity is low, as it does not require sophisticated techniques. Privileges required are also low, suggesting that an attacker could exploit this vulnerability with minimal permissions.
Risk & Impact Analysis
Risk to organizations includes potential data integrity loss and unauthorized modifications, which could disrupt operations. The impact on confidentiality is none, while integrity is high, indicating that the primary concern is the alteration of data.
Given the medium severity and the potential for exploitation, organizations should address this vulnerability in their priority patch cycle. Failure to do so could result in significant operational risks.
