Encode.pm, as distributed in Perl through 5.34.0, allows local users to gain privileges via a Trojan horse Encode::ConfigLocal library (in the current working directory) that preempts dynamic module loading. Exploitation requires an unusual configuration, and certain 2021 versions of Encode.pm (3.05 through 3.11). This issue occurs because the || operator evaluates @INC in a scalar context, and thus @INC has only an integer value.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Encode.pm, as distributed in Perl through 5.34.0, allows local users to gain privileges via a Trojan horse     Encode::ConfigLocal library (in the current working directory) that preempts dynamic module loading.
    Exploitation requires an unusual configuration, and certain 2021 versions of Encode.pm (3.05 through     3.11). This issue occurs because the || operator evaluates @INC in a scalar context, and thus @INC has     only an integer value. (CVE-2021-36770)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote host is affected by the vulnerability described in GLSA-202411-09 (Perl: Multiple Vulnerabilities)

    Multiple vulnerabilities have been discovered in Perl. Please review the CVE identifiers referenced below     for details.

Tenable has extracted the preceding description block directly from the Gentoo Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote CentOS Linux 9 host has packages installed that are affected by a vulnerability as referenced in the perl- Encode-3.08-462.el9 build changelog.

The remote Ubuntu 21.04 host has packages installed that are affected by a vulnerability as referenced in the USN-5033-1 advisory.

    It was discovered that the Perl Encode library incorrectly handled paths. A local attacker could possibly     use this issue to trick the library into executing arbitrary code from the current working directory.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
