A vulnerability was found in GNU Binutils 2.43, classified as problematic. This affects the function xstrdup of the file libiberty/xmalloc.c of the component ld. The manipulation leads to memory leak, which can be initiated remotely. The complexity of an attack is rather high, and the exploitability is reported 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 states that fixes for some leaks will not be committed to the 2.44 branch due to concerns about destabilizing ld, but all reported leaks have been fixed on the binutils master.
Risk to organizations includes potential memory leaks that could compromise system stability. Given the nature of this vulnerability, organizations should prioritize patching within their security protocols. With an exploitability score that suggests difficulty, immediate action is advisable to mitigate any risks associated with this vulnerability.
The low CVSS score of 2.3 indicates that while the vulnerability is not critical, it still poses a risk that should not be overlooked, especially in environments where GNU Binutils is utilized.
Organizations should implement a patch as soon as it becomes available to prevent any potential exploitation of this vulnerability.
Vulnerability Details
A vulnerability was found in GNU Binutils 2.43. It has been classified as problematic and affects the function xstrdup of the file libiberty/xmalloc.c of the component ld. The manipulation leads to a memory leak. It is possible to initiate the attack remotely. The complexity of an attack is rather high, and the exploitability is told to be difficult.
The CVSS score for this vulnerability is 2.3, which is classified as low. The affected product is GNU Binutils, specifically version 2.43.
Technical Analysis
The root cause of this vulnerability is found within the xstrdup function, which is responsible for duplicating strings in memory. The vulnerability leads to a memory leak that can be exploited remotely. The attack vector is network-based, with high complexity, requiring no privileges and passive user interaction.
The vulnerability impacts availability with a low impact score, meaning that while it may not directly cause a service outage, it could lead to performance degradation over time due to memory leaks.
Risk & Impact Analysis
Real-world deployment risk includes potential memory leaks that can affect system performance and stability. Organizations utilizing GNU Binutils must recognize that while the CVSS score is low, the vulnerability could still be exploited in specific scenarios, especially if the component is critical to their operations.
The urgency assessment based on this CVSS score suggests that organizations should schedule remediation in their patch cycles. Although the exploitation complexity is high, organizations should not underestimate the potential impact of this vulnerability.
