(C �� GLOB_ALTDIRFUNC �ǥ��ꥨ�顼 (CVE-2011-2728)) =begin original Calling C with the unsupported flag GLOB_ALTDIRFUNC would cause an access violation / segfault. A Perl program that accepts a flags value from an external source could expose itself to denial of service or arbitrary code execution attacks. There are no known exploits in the wild. The problem has been corrected by explicitly disabling all unsupported flags and setting unused function pointers to null.

A flaw in versions of perl before 5.15.5 can escalate that into a heap buffer overrun; coupled with versions of glibc before 2.16, it possibly allows the execution of arbitrary code. =end original ����Ԥ� perl �� 'x' ʸ���󷫤��֤��黻�ҤΥ�����Ȥ����Ǥ���褦�� �ޤ��� perl �����ɤϡ����˥���ϳ饵���ӥ����ݹ������������� ��ǽ��������ޤ��� 5.15.5 �����ΥС������� perl �η�٤ϡ������ҡ��ץХåե������С����� �������졼�Ȥ����뤳�ȤǤ�; 2.16 �����С������Τ� glib �Ȥ��Ȥ߹�碌�ǡ� Ǥ�դΥ����ɤμ¹Ԥ������ǽ��������ޤ��� =begin original This problem has been fixed. =end original ��������Ͻ�������ޤ����� =head1 Incompatible Changes (�ߴ������ʤ��ʤ��ѹ�) =begin original There are no changes intentionally incompatible with 5.12.4.
