[Security Fix]
- perl の util.c の Perl_repeatcpy 関数にはヒープベースのバッファーオーバーフローが存在し， 'x' 文字列繰り返し演算子によって，攻撃者がサービス拒否 (メモリ消費とクラッシュ) を引き起こしたり，任意のコードを実行する可能性のある脆弱性があります。(CVE-2012-5195)
- Perl の CGI.pm モジュールには (1) Set-Cookie あるいは (2) P3P ヘッダの改行を適切にエスケープしておらず，リモートの攻撃者が任意のヘッダを CGI.pm を使用したアプリケーションからのレスポンスへ注入する脆弱性があります。(CVE-2012-5526)
- Perl の Locale::Maketext 実装の Maketext.pm の _compile 関数は，角かっこの表記をコンパイル中にバックスラッシュと完全修飾メソッド名を適切に扱うことができず，アプリケーションへの巧妙に細工された入力によって，攻撃者が任意のコマンドを実行できる脆弱性があります。(CVE-2012-6329)
- Perl のリハッシュメカニズムには，巧妙に細工されたハッシュキーによって，攻撃者がサービス拒否 (メモリの消費とクラッシュ) を引き起こす脆弱性があります。(CVE-2013-1667)

CVE:
CVE-2012-5195
Heap-based buffer overflow in the Perl_repeatcpy function in util.c in Perl 5.12.x before 5.12.5, 5.14.x before 5.14.3, and 5.15.x before 15.15.5 allows context-dependent attackers to cause a denial of service (memory consumption and crash) or possibly execute arbitrary code via the 'x' string repeat operator.

CVE-2012-5526
CGI.pm module before 3.63 for Perl does not properly escape newlines in (1) Set-Cookie or (2) P3P headers, which might allow remote attackers to inject arbitrary headers into responses from applications that use CGI.pm.

CVE-2012-6329
The _compile function in Maketext.pm in the Locale::Maketext implementation in Perl before 5.17.7 does not properly handle backslashes and fully qualified method names during compilation of bracket notation, which allows context-dependent attackers to execute arbitrary commands via crafted input to an application that accepts translation strings from users, as demonstrated by the TWiki application before 5.1.3, and the Foswiki application 1.0.x through 1.0.10 and 1.1.x through 1.1.6.

CVE-2013-1667
The rehash mechanism in Perl 5.8.2 through 5.16.x allows context-dependent attackers to cause a denial of service (memory consumption and crash) via a crafted hash key.
