Summary
Red Hat Security Advisory: kexec-tools security, bug fix, and enhancement update
Notes
Topic
An updated kexec-tools package that resolves three security issues,
fixes several bugs and adds various enhancements is now available for
Red Hat Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.
Details
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. 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 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.
