This vulnerability has a CVSS 3.1 base score of 6.6, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

A flaw was found in sblim-sfcb. A local attacker with access to the system can exploit an unsafe deserialization vulnerability in the provider-manager's inter-process communication (IPC) message parsing. By sending a specially crafted message, the attacker can cause out-of-bounds memory access, leading to the termination of the provider-manager process and a denial of service. This could also potentially result in limited unintended information disclosure.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
