CVE-2013-3077

CVE-2013-3077 describes multiple integer overflows in the IP_MSFILTER and IPV6_MSFILTER features within the FreeBSD kernel's multicast implementation (versions 8.3 through 9.2-PRERELEASE). This vulnerability allows local users to bypass kernel memory restrictions, leading to arbitrary read/write operations and potential privilege escalation. With a CVSS score of 7.2 (High), it has a low attack complexity and requires local access, but can result in complete compromise of confidentiality, integrity, and availability. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion, indicating a low current threat level.
