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 version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2022:0184 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

      CVE-2021-36770:
      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.

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

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

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - 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)

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.

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

According to the versions of the perl-Encode package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - 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 Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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.
