Multiple integer overflows in the IP_MSFILTER and IPV6_MSFILTER features in (1) sys/netinet/in_mcast.c and (2) sys/netinet6/in6_mcast.c in the multicast implementation in the kernel in FreeBSD 8.3 through 9.2-PRERELEASE allow local users to bypass intended restrictions on kernel-memory read and write operations, and consequently gain privileges, via vectors involving a large number of source-filter entries.

Security readout for executives and security teams

CVE-2013-3077 is a FreeBSD kernel flaw in multicast source-filter handling. A local user could trigger integer overflows and bypass intended limits on kernel memory read and write operations, potentially gaining higher privileges. This matters mainly on FreeBSD systems where untrusted or low-privileged local users can run code. Exposure is limited to FreeBSD 8.3 through 9.2-PRERELEASE systems. Risk is highest on multi-user hosts, shared shell systems, appliances based on affected FreeBSD versions, or servers where attackers may already have local code execution. Treat as high priority for affected legacy FreeBSD systems with local users or hosted workloads. The issue is old, but kernel privilege escalation can turn a limited account compromise into full system control. If no affected FreeBSD systems exist, priority is low. Mitigation focus: Review FreeBSD-SA-13:09 for the vendor-approved fix path.; Apply the relevant FreeBSD security update or source patch from official FreeBSD guidance.; Retire or isolate unsupported FreeBSD 8.3 and 9.x prerelease systems..
