CVE-2016-1238 (2016-07-27)

Loading optional modules from . (current directory).

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.

CVE-2011-2939 (2012-01-13)

Off-by-one error in the decode_xs function in Unicode/Unicode.xs in the Encode module before 2.44, as used in Perl before 5.15.6, might allow context-dependent attackers to cause a denial of service (memory corruption) via a crafted Unicode string, which triggers a heap-based buffer overflow.

NAME

Encode::TW - Taiwan-based Chinese Encodings

SYNOPSIS

use Encode qw/encode decode/; 
$big5 = encode("big5", $utf8); # loads Encode::TW implicitly
$utf8 = decode("big5", $big5); # ditto

DESCRIPTION

This module implements Taiwan-based Chinese charset encodings. Encodings supported are as follows.

Canonical   Alias		Description
--------------------------------------------------------------------
big5        /big-?5$/i	The original Big5 encoding
big5-hkscs  /big5-hk(scs)?$/i	Big5 plus Cantonese characters in 
                              Hong Kong
cp950		                Code Page 950 
                              (Big5 + Microsoft vendor mappings)
--------------------------------------------------------------------

To find how to use this module in detail, see Encode.

NOTES

Due to size concerns, EUC-TW (Extended Unix Character) and BIG5PLUS (CMEX's Big5+) are distributed separately on CPAN, under the name Encode::HanExtra. That module also contains extra China-based encodings.

BUGS

The CNS11643 encoding files are not complete (only the first two planes, 11643-1 and 11643-2, exist in the distribution). For common CNS11643 manipulation, please use EUC-TW in Encode::HanExtra, which contains plane 1-7.

ASCII part (0x00-0x7f) is preserved for all encodings, even though it conflicts with mappings by the Unicode Consortium. See

http://www.debian.or.jp/~kubota/unicode-symbols.html.en

to find why it is implemented that way.
