"The remote MiracleLinux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2009-387:10 advisory.

    The kernel packages contain the Linux kernel, the core of any Linux operating system.
    Security bugs fixed by this release:
    CVE-2009-2692
    The Linux kernel 2.6.0 through 2.6.30.4, and 2.4.4 through 2.4.37.4, does not initialize all function
    pointers for socket operations in proto_ops structures, which allows local users to trigger a NULL pointer
    dereference and gain privileges by using mmap to map page zero, placing arbitrary code on this page, and
    then invoking an unavailable operation, as demonstrated by the sendpage operation (sock_sendpage function)
    on a PF_PPPOX socket.
    CVE-2009-2698
    The udp_sendmsg function in the UDP implementation in (1) net/ipv4/udp.c and (2) net/ipv6/udp.c in the
    Linux kernel before 2.6.19 allows local users to gain privileges or cause a denial of service (NULL
    pointer dereference and system crash) via vectors involving the MSG_MORE flag and a UDP socket.
    Other bugs:
     - fixed the behaviour of ethtool when ONBOOT=no
     - fixed race and removed some debug code

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
