A vulnerability was found in GNU Binutils 2.43. It has been rated as problematic. This issue affects the function xmemdup of the file xmemdup.c of the component ld. The manipulation leads to memory leak. The attack may be initiated remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. It is recommended to apply a patch to fix this issue. The code maintainer explains: "I'm not going to commit some of the leak fixes I've been working on to the 2.44 branch due to concern that would destabilise ld. All of the reported leaks in this bugzilla have been fixed on binutils master."
The vulnerability has a CVSS score of 2.3, indicating low severity. The attack vector is network-based, and the attack complexity is rated as high, making exploitation rather difficult. Organizations utilizing GNU Binutils should ensure they are running an updated version to mitigate the risk presented by this vulnerability.
Risk to organizations includes potential memory leaks, which may affect system performance and reliability. Although the exploitation is complex, the possibility of remote attacks necessitates prompt attention. Organizations should prioritize patching immediately.
For further assistance and to validate your remediation strategies, consider engaging in penetration testing to identify similar weaknesses.
Vulnerability Details
A vulnerability was found in GNU Binutils 2.43. It has been rated as problematic. This issue affects the function xmemdup of the file xmemdup.c of the component ld. The manipulation leads to memory leak. The attack may be initiated remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. It is recommended to apply a patch to fix this issue. The code maintainer explains: "I'm not going to commit some of the leak fixes I've been working on to the 2.44 branch due to concern that would destabilise ld. All of the reported leaks in this bugzilla have been fixed on binutils master."
The vulnerability is classified under CWE-401 (Memory Leak) and CWE-404 (Improper Resource Shutdown or Release). The attack vector is network-based, with no privileges required for exploitation.
Technical Analysis
The root cause of this vulnerability is linked to improper handling of memory allocation within the xmemdup function. Attackers may exploit this vulnerability to access memory that should be freed, leading to a memory leak. The attack requires network access, and the complexity is high due to the need for specific conditions and context.
Exploitation does not require any privileges, and user interaction is passive, making it easier for attackers to initiate. However, the high attack complexity limits the likelihood of successful exploitation.
The confidentiality impact is none, and integrity impact is also none. However, the availability impact is rated as low, indicating that while the leak may not crash the system, it can degrade performance.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is moderate, primarily due to its potential to cause performance degradation over time. Organizations using GNU Binutils 2.43 should recognize that, while the risk is lower than other vulnerabilities, it remains a concern due to the possibility of remote attacks.
Urgently addressing the issue by applying the recommended patches is essential to reduce the risk of exploitation. Organizations should schedule remediation based on their patch management strategies.
