kexec-tools is vulnerable to information disclosure. mkdumprd included unneeded sensitive files (such as all files from the β/root/.ssh/β directory and the hostβs 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 β/etc/kdump.confβ are included in the initrd. The default is the key generated when running the βservice kdump propagateβ command, β/root/.ssh/kdump_id_rsaβ.
