Fedora 26: Update For Perltidy Moderate Symlink Attack Risk

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.
