Bug description:
  An integer overflow, leading to buffer overflow flaw was found in the
  way the implementation of strcoll() routine, used to compare two
  strings based on the current locale, of glibc, the GNU libc libraries,
  performed calculation of memory requirements / allocation, needed for
  storage of the strings. If an application linked against glibc was
  missing an application-level sanity checks for validity of strcoll()
  arguments and accepted untrusted input, an attacker could use this
  flaw to cause the particular application to crash or, potentially,
  execute arbitrary code with the privileges of the user running the
  application.
