CVE-2021-36770 (2021-07-17)

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.

NAME

encguess - guess character encodings of files

VERSION

$Id: encguess,v 0.2 2016/08/04 03:15:58 dankogai Exp $

SYNOPSIS

encguess [switches] filename...

SWITCHES

-h

show this message and exit.

-s

specify a list of "suspect encoding types" to test, seperated by either : or ,

-S

output a list of all acceptable encoding types that can be used with the -s param

-u

suppress display of unidentified types

EXAMPLES:

  • Guess encoding of a file named test.txt, using only the default suspect types.

    encguess test.txt

  • Guess the encoding type of a file named test.txt, using the suspect types euc-jp,shiftjis,7bit-jis.

    encguess -s euc-jp,shiftjis,7bit-jis test.txt
encguess -s euc-jp:shiftjis:7bit-jis test.txt

  • Guess the encoding type of several files, do not display results for unidentified files.

    encguess -us euc-jp,shiftjis,7bit-jis test*.txt

DESCRIPTION

The encoding identification is done by checking one encoding type at a time until all but the right type are eliminated. The set of encoding types to try is defined by the -s parameter and defaults to ascii, utf8 and UTF-16/32 with BOM. This can be overridden by passing one or more encoding types via the -s parameter. If you need to pass in multiple suspect encoding types, use a quoted string with the a space separating each value.
