Fedora 20: mksh Security Update
Summary
mksh is the MirBSD enhanced version of the Public Domain Korn shell (pdksh),
a bourne-compatible shell which is largely similar to the original AT&T Korn
shell. It includes bug fixes and feature improvements in order to produce a
modern, robust shell good for interactive and especially script use, being a
bourne shell replacement, pdksh successor and an alternative to the C shell.
Update Information:
R50f is a required security and bugfix release:
* Add a patch marker for vendor patch versioning to mksh.1 * SECURITY: make unset HISTFILE actually work * Document some more issues with the current history code * Remove some unused code * RCSID-only sync with OpenBSD, for bogus and irrelevant changes * Also disable field splitting for alias 'local= ypeset' * Fix read -n-1 to not be identical to read -N-1 * Several fixes and improvements to lksh(1) and mksh(1) manpages * More code (int → size_t), comment and testsuite fixes * Make dot.mkshrc more robust (LP#1441853) * Fix issues with IFS='' read, found by edualbus * Fix integer overflows related to file descriptor parsing, found by Pawel Wylecial (LP#1440685); reduce memory usage for I/O redirs * Document in the manpage how to set ±U according to the current locale settings via LANG/LC_* parameters (cf. Debian #782225) * Some code cleanup and restructuring * Handle number parsing and storing more carefully
