Description Robert Buchholz (RETIRED) gentoo-dev 2008-07-02 23:29:50 UTC 
CVE-2008-2372 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-2372):
  The Linux kernel 2.6.24 and 2.6.25 before 2.6.25.9 allows local users to
  cause a denial of service (memory consumption) via a large number of calls to
  the get_user_pages function, which lacks a ZERO_PAGE optimization and results
  in allocation of "useless newly zeroed pages."

Note: >=genpatches-2.6.25-7 is unaffected. Removing hardened as there are no vulnerable versions of hardened-sources in portage.
