A vulnerability classified as problematic has been found in GNU Binutils 2.43. The affected function is xstrdup within the file xstrdup.c of the component ld. This vulnerability allows for a memory leak, which can be exploited remotely. Although the complexity of an attack is rated as high, it is important to note that the exploit has been disclosed publicly and may be used.
The code maintainer has indicated that certain leak fixes will not be committed to the 2.44 branch due to concerns that this may destabilize ld. However, all reported leaks related to this vulnerability have been resolved in the binutils master branch. Organizations should prioritize patching immediately.
With a CVSS score of 2.3, this vulnerability is classified as low severity. Despite its low score, the potential for exploitation remains a risk to organizations, particularly in environments where GNU Binutils is deployed.
Given the exploitability challenges and the required technical knowledge to launch an attack, organizations should still consider this vulnerability serious enough to warrant prompt remediation.
In summary, the urgency for defending against CVE-2025-1152 lies in the necessity to patch systems and reduce the risk of memory leaks that could lead to more severe issues in the future.
Vulnerability Details
The vulnerability affects GNU Binutils version 2.43, specifically the xstrdup function in the ld component. The nature of the vulnerability leads to a memory leak, making it susceptible to remote exploitation. The CWE classifications associated with this vulnerability are CWE-401 (Memory Leak) and CWE-404 (Improper Resource Shutdown or Release).
The CVSS score of 2.3 indicates low severity, reflecting the low impact on confidentiality and integrity, while the availability impact is noted as low. The vulnerability was published on February 10, 2025.
Technical Analysis
The root cause of this vulnerability lies in the function xstrdup, which fails to properly manage memory allocation leading to leaks. The attack vector is through the network, with a high attack complexity indicating that an attacker needs a specific skill set to exploit it. No privileges are required to initiate the attack, and user interaction is passive, which means the attack does not necessitate involvement from the targeted user.
The impacts on confidentiality and integrity are noted as none, while the availability impact is low. This means that while the attack may not directly affect the data integrity or confidentiality, it could lead to resource depletion, affecting the system's availability.
Risk & Impact Analysis
Risk to organizations includes the potential for denial of service due to memory leaks, which could exhaust system resources. Although the CVSS score indicates low severity, the ability to exploit this vulnerability remotely presents a risk that should not be overlooked.
Organizations using GNU Binutils should assess their exposure and the potential impact on their operations. The blast radius, although limited, could still disrupt critical services if left unaddressed, especially in systems where GNU Binutils is a core component.
