A vulnerability has been found in GNU Binutils 2.43 and classified as problematic. Affected by this vulnerability is the function __sanitizer::internal_strlen of the file binutils/nm.c of the component nm. The manipulation of the argument const leads to buffer overflow. The attack can be launched remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used.
Given the low CVSS score of 2.3, the urgency for defenders is moderate. Organizations should schedule remediation, as the potential for exploitation, while not imminent, still poses a risk.
The vulnerability has been classified under CWE-119 and CWE-120, indicating issues related to improper restriction of operations within the bounds of a memory buffer, and potential buffer overflow vulnerabilities.
As of now, there are no known exploits available, and the vulnerability is not classified as actively exploited in the wild. However, as a precaution, organizations should remain vigilant.
Organizations using GNU Binutils should prioritize updates to version 2.43 or later to mitigate this vulnerability.
Vulnerability Details
The vulnerability affects GNU Binutils 2.43, specifically within the function __sanitizer::internal_strlen located in the binutils/nm.c file. The CVSS score for this vulnerability is 2.3, classified as low severity.
The attack vector is network-based, and the attack complexity is high, meaning that it requires specific conditions to be successful. There are no privileges required to exploit this vulnerability, but user interaction is passive.
The availability impact is low, indicating that while the system may not be fully compromised, there is still potential for service disruption.
Technical Analysis
The root cause of this vulnerability is the improper handling of memory buffers in the function __sanitizer::internal_strlen. This flaw allows an attacker to craft arguments that lead to a buffer overflow, potentially allowing arbitrary code execution.
The attack vector for this vulnerability is through network interactions, which means that an attacker can exploit it without physical access to the system.
Attack complexity is classified as high, suggesting that the attacker would need specific knowledge or conditions to successfully exploit the vulnerability.
No privileges are required for exploitation, and user interaction is passive, meaning that users do not need to perform any actions to trigger the vulnerability.
Risk & Impact Analysis
Risk to organizations includes potential service disruption due to buffer overflow, albeit the likelihood of successful exploitation is low due to the high complexity of the attack.
Organizations using affected versions of GNU Binutils should assess their exposure and implement necessary updates.
Given the nature of this vulnerability, it is advisable for organizations to maintain monitoring for any signs of exploitation attempts.
With a CVSS 4.0 vector score indicating various impacts, it reinforces the importance of proactive vulnerability management and response strategies.
