CVE-2015-8607: Input Validation
First published: Wed Jan 13 2016(Updated: )
The canonpath function in the File::Spec module in PathTools before 3.62, as used in Perl, does not properly preserve the taint attribute of data, which might allow context-dependent attackers to bypass the taint protection mechanism via a crafted string.
