  system cannot function properly.

  It was discovered that the formatted printing functionality in glibc did
  not properly restrict the use of alloca(). This could allow an attacker to
  bypass FORTIFY_SOURCE protections and execute arbitrary code using a format
  string flaw in an application, even though these protections are expected
  to limit the impact of such flaws to an application abort. (CVE-2012-3406)

  This update also fixes the following bug:

  * If a file or a string was in the IBM-930 encoding, and contained the
  invalid multibyte character '0xffff', attempting to use iconv() (or the
  iconv command) to convert that file or string to another encoding, such as
  UTF-8, resulted in a segmentation fault. With this update, the conversion
  code for the IBM-930 encoding recognizes this invalid character and calls
  an error handler, rather than causing a segmentation fault. (BZ#837896)

  All users of glibc are advised to upgrade to these updated packages, which
  contain backported patches to fix these issues.");
