A vulnerability, which was classified as critical, was found in GNU elfutils 0.192. This affects the function process_symtab of the file readelf.c of the component eu-readelf. The manipulation of the argument D/a leads to buffer overflow. Local access is required to approach this attack. The exploit has been disclosed to the public and may be used. The identifier of the patch is 5e5c0394d82c53e97750fe7b18023e6f84157b81. It is recommended to apply a patch to fix this issue.
Organizations should prioritize patching immediately. Risk to organizations includes potential unauthorized access and modification of sensitive data due to the buffer overflow vulnerability. Given the critical nature of this vulnerability, local users may exploit it if not addressed promptly.
The CVSS score for this vulnerability is 4.8, indicating a medium severity level. This score suggests that while the vulnerability is serious, it requires local access, which may limit the attack surface compared to network-exploitable vulnerabilities.
Organizations should assess their usage of GNU elfutils and apply the recommended patch to mitigate risks associated with this vulnerability.
Vulnerability Details
A vulnerability, which was classified as critical, was found in GNU elfutils 0.192. This affects the function process_symtab of the file readelf.c of the component eu-readelf. The manipulation of the argument D/a leads to buffer overflow. Local access is required to approach this attack. The exploit has been disclosed to the public and may be used. The identifier of the patch is 5e5c0394d82c53e97750fe7b18023e6f84157b81. It is recommended to apply a patch to fix this issue.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of input arguments within the process_symtab function, leading to a buffer overflow condition. Attackers may exploit this vulnerability by manipulating the input to exceed allocated buffer sizes.
The attack vector for this vulnerability is local, meaning that an attacker must have local access to the system to exploit it. The attack complexity is low, utilizing straightforward input manipulation techniques to trigger the buffer overflow.
Privileges required to exploit this vulnerability are low, as attackers with basic user permissions may execute the exploit. User interaction is not required, further increasing the risk of exploitation.
The impact on confidentiality, integrity, and availability is categorized as low, as the buffer overflow may not directly result in significant system failures but can lead to unauthorized access and data manipulation.
Risk & Impact Analysis
Real-world deployment risk associated with this vulnerability is moderate, primarily due to the local access requirement. However, if exploited, it can lead to significant consequences, including unauthorized access to sensitive data or system control.
Organizations that utilize GNU elfutils should be aware of the potential for exploitation and take immediate action to apply the necessary patches. The urgency assessment indicates that organizations should address this vulnerability in their priority patch cycle.
The blast radius of this vulnerability may vary based on the organization's environment and the deployment of GNU elfutils across systems. Organizations should consider their specific configurations and user access patterns when evaluating their risk.
