"The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2011-80:02 advisory.

    The kernel package contains the Linux kernel (vmlinuz), the core of any
    Linux operating system.  The kernel handles the basic functions of the operating system: memory
    allocation, process allocation, device input and output, etc.
    Security issues fixed with this release:
    CVE-2010-4165
    The do_tcp_setsockopt function in net/ipv4/tcp.c in the Linux kernel before 2.6.37-rc2 does not properly
    restrict TCP_MAXSEG (aka MSS) values, which allows local users to cause a denial of service (OOPS) via a
    setsockopt call that specifies a small value, leading to a divide-by-zero error or incorrect use of a
    signed integer.
    CVE-2010-4169
    Use-after-free vulnerability in mm/mprotect.c in the Linux kernel before 2.6.37-rc2 allows local users to
    cause a denial of service via vectors involving an mprotect system call.
    CVE-2010-4243
    fs/exec.c in the Linux kernel before 2.6.37 does not enable the OOM Killer to assess use of stack memory
    by arrays representing the (1) arguments and (2) environment, which allows local users to cause a denial
    of service (memory consumption) via a crafted exec system call, aka an OOM dodging issue, a related issue
    to CVE-2010-3858.

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