Bug Fix Advisory

Topic

An updated setup package that fixes various bugs is now available for Red Hat
Enterprise Linux 5.

Description

The setup package contains a set of important system configuration and setup
files, such as passwd, group, and profile.

This update fixes the following bugs:

• Prior to this update, the setup package did not reserve the group ID (GID) for
  the group wbpriv 88, used for sharing the permissions of sockets with Squid. As
  a consequence, other packages or system administrators could accidentally assign
  this group number to another group. With this update, the setup package reserves
  this GID name and number so that accidental conflicts with other users and
  groups no longer happen. (BZ#501762)
  
• Prior to this update, the /etc/hosts.deny configuration file contained an old
  comment about the redundant portmap line. This could cause confusion. With this
  update, this comment has been removed from the hosts.deny configuration file.
  (BZ#509919)
  
• Prior to this update, /etc/profile.d/ scripts umask modifications were not
  respected in the bash and the korn shell (ksh) login shell. This update corrects
  this behavior, so that umask modifications from /etc/profile.d scripts in bash
  and ksh login shell are again respected. (BZ#608987)
  
• Prior to this update, the /etc/profile script used the PS1 environmental
  variable for detecting interactive shell, which is not portable because this
  variable is set after the profile script execution the PS1 in the Korn shell. As
  a consequence, every ksh shell was treated as non-interactive and did not
  display the output from the profile.d scripts. This update uses a portable
  variable for interactive shell detection. Now, also ksh users can see the output
  of /etc/profile.d/ scripts in interactive shells. (BZ#616116)
  
• Prior to this update, /etc/profile.d/ scripts umask modifications were not
  respected in the tcsh login shell. With this update, all umask modifications
  from /etc/profile.d scripts in the tcsh login shell are again respected.
  (BZ#617495)
  
• Prior this update, /etc/bashrc script wrongly used two echo commands in
  PROMPT_COMMAND environment variable. As a consequence, the output of the
  terminal could, under certain circumstances, be placed into the terminal title.
  With this update, the bashrc script uses one single printf command in the
  PROMPT_COMMAND environment variable. (BZ#620443)
  
• Prior to this update, the PROMPT_COMMAND variable set by a custom profile.d
  script was overwritten with the default value from the /etc/bashrc script file.
  With this update, the /etc/bashrc script file has been updated so that it now
  respects a user-defined PROMPT_COMMAND variable, and does not overwrite it.
  (BZ#691430)
  
• Prior to this update, the /etc/host.conf file contained the redundant line
  "order host,bind", hwich the glibc library no longer uses. With this update,
  this line has been removed from the host.conf file. (BZ#703051)
  
• Prior to this update, the environmental variable PATH in the tcsh login shell
  contained remnants of the X11R6 hierarchy (/usr/X11R6/bin). This could confuse
  users because users of the bash/ksh login shell do not have this directory in
  PATH envvar. With this update, these remnants have been removed. (BZ#760241)
  

All users are advised to upgrade to this updated setup package, which fixes
these bugs.
