Description Michael Harrison 2011-10-05 07:15:17 UTC
Multiple security flaws were found in the way kexec-tools performed management
of created kdump core files and ramdisk images:
* the default value of "StrictHostKeyChecking=no" has been used for kdump /
  mkdumprd openssh integration. A remote malicious kdump server could use
  this flaw to impersonate the intended, correct kdump server to obtain
  security sensitive information (kdump core files),
* mkdumprd utility copied content of certain directories into newly created
  initial ramdisk images, potentially leading to information leak,
* mkdumprd utility created the final initial ramdisk image with world-readable
  permissions, possibly leading to information leak.

Changed CVE per: http://www.openwall.com/lists/oss-security/2011/10/10/1
Comment 2 Justin Lecher (RETIRED) gentoo-dev 2013-03-27 08:42:52 UTC
I am pretty sure this doesn't apply to us. We don't have any support for kdump through initscripts. Could someone please cross check that this is really only about the redhat/fedora init scripts of kdump?
Comment 3 Aaron Bauman (RETIRED) gentoo-dev 2016-03-02 10:00:55 UTC
This only applies to redhat/fedora and kexec-tools 1.x before 1.102pre-154 and 2.x before 2.0.0-209.  None of these are in Portage.  Per previous comment we do not even support the initscripts referenced in RHEL.
