Description Stefan Behte (RETIRED) gentoo-dev Security 2008-10-21 22:14:28 UTC 
CVE-2008-4410 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-4410):
  The vmi_write_ldt_entry function in arch/x86/kernel/vmi_32.c in the
  Virtual Machine Interface (VMI) in the Linux kernel 2.6.26.5 invokes
  write_idt_entry where write_ldt_entry was intended, which allows
  local users to cause a denial of service (persistent application
  failure) via crafted function calls, related to the Java Runtime
  Environment (JRE) experiencing improper LDT selector state, a
  different vulnerability than CVE-2008-3247.
Comment 1 Stefan Behte (RETIRED) gentoo-dev Security 2008-10-21 22:26:18 UTC 
Excluding hardened, they have >= 2.6.26.7 (sorry guys).
Comment 2 Stefan Behte (RETIRED) gentoo-dev Security 2008-10-21 22:28:23 UTC 
Damn, xcuse my bugspam.
According to http://www.securityfocus.com/bid/31565 this affects higher kernel versions as well.
Comment 3 kfm 2009-07-20 20:32:52 UTC 
hardened-kernel unaffected at present time. Removing alias.

PS: genpatches-2.6.26-3 added 2.6.26.6. =genpatches-2.6.25* remains vulnerable. However, hardened-sources-2.6.25-r13 does not because we independently folded in the newer stable patches out of necessity :p
