Description GLSAMaker/CVETool Bot gentoo-dev 2011-10-08 17:31:45 UTC
CVE-2011-2928 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-2928):
  The befs_follow_link function in fs/befs/linuxvfs.c in the Linux kernel
  before 3.1-rc3 does not validate the length attribute of long symlinks,
  which allows local users to cause a denial of service (incorrect pointer
  dereference and OOPS) by accessing a long symlink on a malformed Be
  filesystem.
