The remote Redhat Enterprise Linux 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2011:1532 advisory.

    Kexec allows for booting a Linux kernel from the context of an already     running kernel.

    Kdump used the SSH (Secure Shell) StrictHostKeyChecking=no option when     dumping to SSH targets, causing the target kdump server's SSH host key not     to be checked. This could make it easier for a man-in-the-middle attacker     on the local network to impersonate the kdump SSH target server and     possibly gain access to sensitive information in the vmcore dumps.
    (CVE-2011-3588)

    mkdumprd created initrd files with world-readable permissions. A local user     could possibly use this flaw to gain access to sensitive information, such     as the private SSH key used to authenticate to a remote server when kdump     was configured to dump to an SSH target. (CVE-2011-3589)

    mkdumprd included unneeded sensitive files (such as all files from the     /root/.ssh/ directory and the host's private SSH keys) in the resulting     initrd. This could lead to an information leak when initrd files were     previously created with world-readable permissions. Note: With this update,     only the SSH client configuration, known hosts files, and the SSH key     configured via the newly introduced sshkey option in /etc/kdump.conf are     included in the initrd. The default is the key generated when running the     service kdump propagate command, /root/.ssh/kdump_id_rsa.
    (CVE-2011-3590)

    Red Hat would like to thank Kevan Carstensen for reporting these issues.

    This update also fixes several bugs and adds various enhancements.
    Space precludes documenting all of these changes in this advisory.
    Documentation for these bug fixes and enhancements will be available     shortly from the Technical Notes document, linked to in the References     section.

    All kexec-tools users should upgrade to this updated package, which     contains backported patches to resolve these issues and add these     enhancements.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

The remote Redhat Enterprise Linux 5 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2012:0152 advisory.

    The kexec-tools package contains the /sbin/kexec binary and utilities that     together form the user-space component of the kernel's kexec feature. The     /sbin/kexec binary facilitates a new kernel to boot using the kernel's     kexec feature either on a normal or a panic reboot. The kexec fastboot     mechanism allows booting a Linux kernel from the context of an already     running kernel.

    Kdump used the SSH (Secure Shell) StrictHostKeyChecking=no option when     dumping to SSH targets, causing the target kdump server's SSH host key not     to be checked. This could make it easier for a man-in-the-middle attacker     on the local network to impersonate the kdump SSH target server and     possibly gain access to sensitive information in the vmcore dumps.
    (CVE-2011-3588)

    The mkdumprd utility created initrd files with world-readable permissions.
    A local user could possibly use this flaw to gain access to sensitive     information, such as the private SSH key used to authenticate to a remote     server when kdump was configured to dump to an SSH target. (CVE-2011-3589)

    The mkdumprd utility included unneeded sensitive files (such as all files     from the /root/.ssh/ directory and the host's private SSH keys) in the     resulting initrd. This could lead to an information leak when initrd     files were previously created with world-readable permissions. Note: With     this update, only the SSH client configuration, known hosts files, and the     SSH key configured via the newly introduced sshkey option in     /etc/kdump.conf are included in the initrd.

    Red Hat would like to thank Kevan Carstensen for reporting these issues.

    This updated kexec-tools package also includes numerous bug fixes and     enhancements. Space precludes documenting all of these changes in this     advisory. Users are directed to the Red Hat Enterprise Linux 5.8 Technical     Notes, linked to in the References, for information on the most significant     of these changes.

    All users of kexec-tools are advised to upgrade to this updated package,     which resolves these security issues, fixes these bugs and adds these     enhancements.

The remote MiracleLinux 4 host has a package installed that is affected by multiple vulnerabilities as referenced in the AXSA:2012-12:01 advisory.

    kexec-tools provides /sbin/kexec binary that facilitates a new kernel to boot using the kernel's kexec     feature either on a normal or a panic reboot. This package contains the /sbin/kexec binary and ancillary     utilities that together form the userspace component of the kernel's kexec feature.
    Security issues fixed with this release:
    CVE-2011-3588     CVE-2011-3589     CVE-2011-3590     No information available at the time of writing, see the CVE link below.
    Fixed bugs:
     - Because the mkdumprd utility failed to parse the /etc/mdadm.conf file, it also failed to create an     initial ramdisk for kdump crash recovery. This has been fixed and the kdump service now starts as     expected.
     - On PowerPC 64 systems with more than 1 TB of RAM, the kexec utility experienced a segmentation fault     upon kdump starting. This has been fixed and kexec does not crash any more when kdump starts and works as     expected.
