Name of the Vulnerable Software and Affected Versions OpenBSD Kernel (affected versions not specified)

Description This issue allows local attackers to disclose sensitive information on affected installations. An attacker must first obtain the ability to execute low-privileged code on the target system. The flaw exists within the implementation of multicast routing, resulting from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this in conjunction with other issues to escalate privileges and execute arbitrary code in the context of the kernel.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
