Vulnerability Details
The official CVE description for CVE-2023-47995 states: 'Memory Allocation with Excessive Size Value discovered in BitmapAccess.cpp::FreeImage_AllocateBitmap in FreeImage 3.18.0 allows attackers to cause a denial of service.' This vulnerability is categorized under CWE-120, which refers to buffer allocation issues.
The CVSS score of 6.5 is derived from the following parameters: the attack vector is network-based, the attack complexity is low, and no privileges are required to exploit the vulnerability. User interaction is required, which slightly mitigates the risk, but the high impact on availability remains a concern.
The affected product is FreeImage, specifically version 3.18.0. Organizations using this version should take immediate action to remediate the vulnerability.
Technical Analysis
The root cause of CVE-2023-47995 lies in improper handling of memory allocation within the FreeImage library. Specifically, excessive size values can be passed, leading to an allocation that overwhelms the available memory, resulting in a denial of service.
The attack vector for this vulnerability is network-based, meaning that an attacker can exploit it remotely. The attack complexity is classified as low, indicating that successful exploitation can be achieved with relatively straightforward techniques.
Exploitation of this vulnerability does not require any user privileges, making it more accessible for attackers. User interaction is required, which means that the target user must perform an action that triggers the vulnerability.
The potential impacts of a successful exploit include high availability impact, as the service may become unresponsive. Confidentiality and integrity impacts are not affected, which indicates that data is not at risk of being exposed or altered.
Risk & Impact Analysis
The real-world risk of CVE-2023-47995 is significant, as it highlights a vulnerability that could be exploited to disrupt services. Organizations using FreeImage 3.18.0 should be particularly cautious, as the denial of service could affect critical applications and services.
The urgency for organizations to address this vulnerability is underscored by its CVSS score of 6.5, which falls into the medium severity category. Organizations should assess their exposure and prioritize remediation efforts accordingly.
With the potential for service disruption, the blast radius of this vulnerability extends to all services relying on FreeImage 3.18.0, emphasizing the need for immediate action.
