Affected Products:
  • SUSE Linux Enterprise Module for Basesystem 15

An update that has three recommended fixes can now be installed.


This update for bash provides the following fixes:

  • Bugfix: Parse settings in inputrc for all screen TERM variables starting with "screen." (bsc#1095661)
  • Make the generation of bash.html reproducible. (bsc#1100488)
  • Use initgroups(3) instead of setgroups(2) to fix the usage of suid programs. (bsc#1095670)
  • Fix a problem that could cause hash table bash uses to store exit statuses from asynchronous processes to develop loops in circumstances involving long-running scripts that create and reap many processes.
  • Fix a problem that could cause the shell to loop if a SIGINT is received inside of a SIGINT trap handler.
  • Fix cases where a failing readline command (e.g., delete-char at the end of a line) can cause a multi-character key sequence to 'back up' and attempt to re-read some of the characters in the sequence.
  • Fix a problem when sourcing a file from an interactive shell, that setting the SIGINT handler to the default and typing ^C would cause the shell to exit.
