Description Robert Buchholz (RETIRED) gentoo-dev 2007-11-12 23:32:01 UTC 
CVE-2007-5908 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2007-5908):
  Buffer overflow in the (1) sysfs_show_available_clocksources and (2)
  sysfs_show_current_clocksources functions in Linux kernel 2.6.23 and earlier
  might allow local users to cause a denial of service or execute arbitrary
  code via crafted clock source names.
Comment 1 Robert Buchholz (RETIRED) gentoo-dev 2007-12-01 23:16:01 UTC 
** REJECT ** Buffer overflow in the (1) sysfs_show_available_clocksources and (2) sysfs_show_current_clocksources functions in Linux kernel 2.6.23 and earlier might allow local users to cause a denial of service or execute arbitrary code via crafted clock source names. NOTE: follow-on analysis by Linux developers states that "There is no way for unprivileged users (or really even the root user) to add new clocksources."
