DESCRIPTION:
Red Hat has issued an update for kexec-tools. This fixes two security
issues, which can be exploited by malicious, local users and malicious
people to disclose sensitive information.
1) The security issue is caused due to the mkdumprd utility setting
the "StrictHostKeyChecking" SSH-Parameter to "no" when using SSH
targets, which can aid the disclosure of e.g. kdump core files by
impersonating a kdump SSH server target via Man-in-the-Middle (MitM)
attacks.
2) The security issue is caused due to the mkdumprd utility creating
an initrd file with world-readable permissions, which can be
exploited to disclose the e.g. private SSH key for a remote server
when using SSH targets.
SOLUTION:
Updated packages are available via Red Hat Network.
