CVE-2023-5341 is a heap use-after-free vulnerability identified in the bmp.c coder module of ImageMagick, a widely used image processing library. This flaw exists in Red Hat Enterprise Linux 6 distributions that include ImageMagick. A use-after-free occurs when a program continues to use memory after it has been freed, potentially leading to memory corruption, crashes, or denial of service. The vulnerability has a CVSS 3.1 base score of 6.2, indicating medium severity. The attack vector is local (AV:L), meaning an attacker must have local access to the system to exploit it. The attack complexity is low (AC:L), no privileges are required (PR:N), and no user interaction is needed (UI:N). The impact is limited to availability (A:H), with no confidentiality or integrity impact. This suggests that exploitation could cause a denial of service by crashing the ImageMagick process or related services that utilize it. No known exploits have been reported in the wild, and no patches or mitigations are linked in the provided data, indicating that organizations should monitor vendor advisories for updates. The vulnerability affects legacy systems, as RHEL 6 is an older release, but ImageMagick remains a common component in many Linux environments, especially for image processing tasks in web services or internal tools.

For European organizations, the primary impact of CVE-2023-5341 is potential denial of service on systems running Red Hat Enterprise Linux 6 with ImageMagick installed. This could disrupt services that rely on image processing, such as web applications, content management systems, or automated workflows. Although the vulnerability does not compromise data confidentiality or integrity, availability disruptions can affect business operations and service reliability. Organizations using legacy RHEL 6 systems, which may still be in use in some sectors due to long-term support contracts or legacy application dependencies, are most at risk. The lack of known exploits reduces immediate threat but does not eliminate risk, especially if attackers develop local exploits. Given the local attack vector, insider threats or compromised user accounts could leverage this vulnerability to cause service outages. The impact is less severe for organizations that have migrated to newer OS versions or do not use ImageMagick in vulnerable configurations.

European organizations should first verify if Red Hat Enterprise Linux 6 systems with ImageMagick are in use, particularly those processing BMP images. Since no patch links are provided, organizations should monitor Red Hat security advisories for official patches or updates addressing CVE-2023-5341. In the interim, restricting local access to trusted users only and employing strict user privilege management can reduce exploitation risk. Disabling or removing ImageMagick on systems where it is not essential can eliminate the attack surface. For systems requiring ImageMagick, consider isolating image processing tasks in sandboxed environments or containers to limit impact. Regularly auditing and monitoring system logs for crashes or abnormal behavior related to ImageMagick can help detect exploitation attempts early. Planning migration from RHEL 6 to supported versions will also mitigate exposure to this and other legacy vulnerabilities.
