The mipv6 daemon in UMIP 0.4 does not verify that netlink messages originated in the kernel, which allows local users to spoof netlink socket communication via a crafted unicast message.

the mipv6 daemon did not check the origin of netlink messages, therefore allowing local users to spoof messages (CVE-2010-2522).
remote attackers could cause buffer overflows in mipv6d (CVE-2010-2523).

The following issues have been fixed :

  - the mipv6 daemon did not check the origin of netlink     messages, therefore allowing local users to spoof     messages. (CVE-2010-2522)

  - remote attackers could cause buffer overflows in mipv6d.
    (CVE-2010-2523)

This update fixes two security problems in mipv6-daemon: I) CVE-2010-2522: The origin of netlink messages sent to mipv6-daemon was not verified, allowing for local users to spoof netlink messages and thus influence the behaviour of mipv6-daemon. II) CVE-2010-2523: A specially crafted ND_OPT_PREFIX_INFORMATION or ND_OPT_HOME_AGENT_INFO packet could be used to exploit a buffer overflow in mipv6-daemon.
