Fedora 25 : perltidy (2017-a3c7d077c7)

medium Nessus Plugin ID 100732

Language:

Synopsis

The remote Fedora host is missing a security update.

Description

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected perltidy package.
