"The remote MiracleLinux 3 host has packages installed that are affected by a vulnerability as referenced in the
AXSA:2012-1010:08 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-2012-2100
    The ext4_fill_flex_info function in fs/ext4/super.c in the Linux kernel before 3.2.2, on the x86 platform
    and unspecified other platforms, allows user-assisted remote attackers to trigger inconsistent filesystem-
    groups data and possibly cause a denial of service via a malformed ext4 filesystem containing a super
    block with a large FLEX_BG group size (aka s_log_groups_per_flex value). NOTE: this vulnerability exists
    because of an incomplete fix for CVE-2009-4307.

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

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
