Encode.pm, as distributed in Perl through 5.34.0, allows local users togain privileges via a Trojan horse Encode::ConfigLocal library (in thecurrent working directory) that preempts dynamic module loading.Exploitation requires an unusual configuration, and certain 2021 versionsof Encode.pm (3.05 through 3.11). This issue occurs because the || operatorevaluates @INC in a scalar context, and thus @INC has only an integervalue.
