| Doc Text: |
A flaw was found in perl-Encode, where the Perl5 Encode module loaded modules within the current directory. This flaw allows an attacker with write access to the current directory of a Perl5 process to inject arbitrary Perl code when this module is loaded, which can be used for a local privilege escalation. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
