CVE-2023-51792 is classified as a buffer overflow vulnerability found in libde265 version 1.0.12. This vulnerability allows a local attacker to cause a denial of service by manipulating the allocation size, exceeding the maximum supported size of 0x10000000000. The CVSS score for this vulnerability is 3.3, indicating a low severity level. Despite its classification, organizations should not underestimate its impact, particularly in local environments where an attacker may have direct access.
The potential risk to organizations includes service disruptions that could affect user experience and system availability in critical applications. Given the low severity score, it may not seem urgent; however, local exploitation could lead to more significant issues if not addressed promptly. Organizations should prioritize patching this vulnerability as part of their regular security maintenance cycle.
Currently, there is no evidence of public exploits or known active exploitation of this vulnerability. Organizations are encouraged to monitor developments related to this CVE, especially as additional information may emerge. In the meantime, it is advisable to apply relevant patches and updates as they become available.
Organizations should maintain awareness of this vulnerability and consider it during their risk assessments and security reviews. Regular vulnerability scanning and penetration testing can provide further insights into the security posture concerning this and other vulnerabilities.
Vulnerability Details
The vulnerability in question is categorized as a buffer overflow, which can lead to unexpected behavior or crashes in the affected software. The CVSS vector string for CVE-2023-51792 is CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N, showcasing the attack vector as local, with low complexity and low privileges required for exploitation. The integrity impact is classified as low, while the confidentiality and availability impacts are rated as none.
As of the current date, the vulnerability is marked as deferred, indicating that further evaluation may be necessary before final classification or remediation steps are confirmed. Given the nature of buffer overflow vulnerabilities, it is critical for developers and security teams to implement rigorous input validation and memory management practices to mitigate such risks.
Technical Analysis
The root cause of CVE-2023-51792 lies in improper handling of memory allocation in the libde265 library. The attack vector is classified as local, meaning that an attacker must have local access to the system to exploit this vulnerability. The attack complexity is rated as low, indicating that exploitation does not require significant specialized knowledge or resources. Low privileges are required to exploit this vulnerability, and no user interaction is necessary.
The impacts of this vulnerability on confidentiality, integrity, and availability are significant. While the confidentiality impact is none and the availability impact is rated as none, the integrity impact is classified as low. This means that while the attacker cannot necessarily access sensitive data or disrupt services entirely, they may still be able to alter data integrity in a manner that could have downstream effects.
Risk & Impact Analysis
Risk to organizations includes potential denial of service due to the buffer overflow vulnerability. Given that exploitation requires local access, organizations must evaluate their operational environments and access controls to mitigate the risk of internal threats. The blast radius of this vulnerability is relatively contained due to its local nature, but it could lead to greater security concerns if exploited in sensitive areas of a network.
Organizations should assess their current security measures in light of this vulnerability and prioritize patching efforts accordingly. While the CVSS score indicates low severity, the potential for local exploitation necessitates a proactive approach to security management. Regular vulnerability assessments and penetration testing can further assist in identifying and addressing such vulnerabilities.
Urgency for remediation should be assessed based on the specific use case of libde265 within the organization. For environments where this library is integral, organizations should prioritize patching immediately. In cases where the library is not widely deployed, organizations may address remediation within their routine maintenance cycle.
