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::CN - China-based Chinese Encodings

SYNOPSIS

use Encode qw/encode decode/; 
$euc_cn = encode("euc-cn", $utf8);   # loads Encode::CN implicitly
$utf8   = decode("euc-cn", $euc_cn); # ditto

DESCRIPTION

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

  Canonical   Alias		Description
  --------------------------------------------------------------------
  euc-cn      /euc.*cn$/i	EUC (Extended Unix Character)
	      /cn.*euc$/i
  gb2312			The raw (low-bit) GB2312 character map
  gb12345			Traditional chinese counterpart to 
				GB2312 (raw)
  iso-ir-165			GB2312 + GB6345 + GB8565 + additions
  cp936				Code Page 936, also known as GBK 
				(Extended GuoBiao)
  hz				7-bit escaped GB2312 encoding

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

NOTES

Due to size concerns, GB 18030 (an extension to GBK) is distributed separately on CPAN, under the name Encode::HanExtra. That module also contains extra Taiwan-based encodings.

BUGS

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.
