Descriptions

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.

Múltiples desbordamientos de entero en funcionalidades IP_MSFILTER y IPV6_MSFILTER en (1) sys/netinet/in_mcast.c y (2) sys/netinet6/in6_mcast.c en la implementación multicast en el núcleo en FreeBSD 8.3 hasta v9.2-PRERELEASE permiten a los usuarios locales eludir las restricciones previstas en el núcleo de memoria de lectura y escritura de operaciones, y en consecuencia obtener privilegios a través de vectores que implican un gran número de entradas de filtro de origen.

An integer overflow in computing the size of a temporary buffer can result in a buffer which is too small for the requested operation. An unprivileged process can read or write pages of memory which belong to the kernel. These may lead to exposure of sensitive information or allow privilege escalation.
