coreutils bug fix update

Bug Fix Advisory

Topic

Updated coreutils packages that fix several bugs are now available.

Description

The coreutils package contains the core GNU utilities. It is the
combination of the old GNU fileutils, sh-utils, and textutils packages.

These updated packages fix the following bugs:

• The su utility was previously not built with PIE and RELRO enabled,
  as they were in Red Hat Enterprise Linux 5. In this update, it is built
  as a PIE executable and is using RELRO protection. (BZ#630017)
  
• Previously, when reading a line longer than 16KiB, the tac utility
  reallocated its primary buffer. Before exiting, the tac utility tried
  to free the already freed original buffer, which caused a utility crash
  after a double free error displayed. This was fixed and the tac utility
  no longer frees an already freed buffer. (BZ#628212)
  
• Previously, the hardware control flow, DTRDSR, was implemented via
  TC{SG}ETX. This was changed to TC{SG}ET ioctl, which caused the CDTRDSR
  support in stty to fail. This was fixed to allow stty to correctly handle
  CDTRDSR control flow. (BZ#598631)
  
• Previously, the internalization patch for coreutils had an unsafe
  initialization of char* bufops that left bufops uninitialized or
  initialized to NULL on the first usage. This behavior called memmove
  from an incorrect address, namely from address 0 and size 0. This is now
  fixed and bufops is correctly initialized for the first use. (BZ#683799)
  
• Previously, when the multibyte LC_TIME differed from LC_CTYPE, an
  assertion failure caused the sort utility to crash irrespective of the
  parameters provided to it. This is fixed to prevent a crash when the sort
  utility is run and now works as expected. (BZ#649224)
  
• Previously, the information page about 8-bit octal values did not
  mention checking if the value was lower than 256. Due to this, when a
  command like "/bin/echo -e '\0610'" was used, the results were not
  accurate. This is now fixed to provide more accurate information about
  the behavior of octal values. (BZ#660033)
  
• Previously, when the dd utility used pipes, it read and wrote partial
  blocks. When the size of the block written was shorter than the specified
  maximum output block size, the "oflag=direct" would turn off, which
  resulted in degraded I/O performance. The workaround for this behavior,
  which involves the addition of "iflag=fullblock" is now available in the
  information documentation. (BZ#614605)
  
• Previously, the coreutils information page was not sufficiently
  clear about behavior when multiple parent and leaf node directories are
  created. This is now fixed to incorporate additional information in the
  coreutils information page about the @option mode and its behavior when
  combined with the --parents option. (BZ609262)
  
• Previously, documentation for tail command's --sleep-interval option
  did not outline the results of inotify support. This is now fixed and
  the documentation states that with inotify support, the --sleep-interval
  option is only relevant when the tail command reverts to the old
  polling-based method. (BZ#662900)
  

All coreutils users are advised to upgrade to these updated packages,
which resolve these issues.
