Technical Analysis

CVE-2023-47997 is a vulnerability identified in the FreeImage library version 3.18.0, specifically within the BitmapAccess.cpp component's FreeImage_AllocateBitmap function. The flaw leads to an infinite loop condition when processing bitmap allocations. This infinite loop can be triggered by an attacker supplying crafted bitmap data that causes the allocation function to fail to complete normally. The result is a denial of service (DoS) condition as the affected application or service becomes unresponsive or consumes excessive CPU resources. The vulnerability is classified under CWE-835 (Loop with Unreachable Exit Condition), indicating a logic flaw that prevents the loop from terminating. The CVSS v3.1 base score is 6.5 (medium severity), with the vector indicating that the attack can be performed remotely over the network (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R), and impacts availability only (A:H) without affecting confidentiality or integrity. No known exploits are currently reported in the wild, and no patches or vendor advisories have been linked yet. The vulnerability primarily affects applications or services that utilize FreeImage 3.18.0 for bitmap image processing, which may include image editors, graphic design tools, or any software that processes bitmap images using this library. Since the vulnerability requires user interaction, exploitation typically involves tricking a user into opening or processing a maliciously crafted bitmap image file, which then triggers the infinite loop and causes a denial of service.

Potential Impact

For European organizations, the primary impact of CVE-2023-47997 is the potential disruption of services or applications that rely on FreeImage 3.18.0 for bitmap processing. This could affect sectors such as media, publishing, graphic design, and any enterprise software that integrates this library for image handling. The denial of service could lead to temporary loss of productivity, degraded user experience, and potential operational delays. In environments where image processing is part of automated workflows or customer-facing services, this could translate into service outages or degraded availability, impacting business continuity. Although the vulnerability does not compromise data confidentiality or integrity, the availability impact could be significant in high-demand or critical systems. Additionally, since exploitation requires user interaction, phishing or social engineering campaigns could be used to deliver malicious bitmap files, increasing the risk vector. European organizations with strict uptime requirements or those in regulated industries may face compliance and reputational risks if service disruptions occur due to this vulnerability.

Mitigation Recommendations

To mitigate CVE-2023-47997, European organizations should first identify all software and services that incorporate FreeImage 3.18.0, particularly those that process bitmap images from external or untrusted sources. Until an official patch is released, organizations should implement the following specific measures: 1) Restrict or block the acceptance of bitmap image files from untrusted or unknown sources, especially in user-upload scenarios or email attachments. 2) Employ sandboxing or isolated environments for processing bitmap images to contain potential denial of service impacts. 3) Monitor CPU and memory usage of applications using FreeImage to detect abnormal resource consumption indicative of infinite loops. 4) Educate users about the risks of opening unsolicited or suspicious image files, emphasizing the need for caution with bitmap files. 5) Consider deploying application-layer controls or filters that validate and sanitize bitmap images before processing. 6) Stay alert for vendor updates or patches addressing this vulnerability and plan for prompt deployment once available. 7) If feasible, evaluate alternative image processing libraries without this vulnerability for critical applications. These targeted mitigations go beyond generic advice by focusing on controlling input vectors, monitoring resource usage, and isolating vulnerable components to minimize operational impact.
