Fedora 25: perltidy Security Update
Summary
Perltidy is a Perl script that indents and re-formats Perl scripts to
make them easier to read. If you write Perl scripts, or spend much
time reading them, you will probably find it useful. The formatting
can be controlled with command line parameters. The default parameter
settings approximately follow the suggestions in the Perl Style Guide.
Perltidy can also output HTML of both POD and source code. Besides
re-formatting scripts, Perltidy can be a great help in tracking down
errors with missing or extra braces, parentheses, and square brackets
because it is very good at localizing errors.
Cumulative bug-fix, enhancement and security update, including fix for
CVE-2016-10374: perltidy relies on the current working directory for certain
output files and did not have a symlink-attack protection mechanism, which
allowed local users to overwrite arbitrary files by creating a symlink, as
demonstrated by creating a perltidy.ERR symlink that the victim could not
delete.
