CVE:CVE-2007-1661
CNNVD:CNNVD-200711-106
PCRE（Perl Compatible Regular Expressions）是软件开发者Philip Hazel所研发的一个使用C语言编写的开源正则表达式函数库。
pcre处理某些畸形正则表达式的方法存在信息泄露漏洞，非UTF-8模式的多种\X?\d或\P{L}?\d形式可能回退到字符串开始之前，这可能造成泄露地址空间地址或由于越界读取而出现崩溃。
solution:Upgrade pcre perl-compatible_regular_expression_library to a higher version than 7.2,7.0,7.1,and avoid the version (,7.2],7.0,7.1; Upgrade apple mac_os_x to a higher version than 10.4.11,and avoid the version 10.4.11; Upgrade apple mac_os_x_server to a higher version than 10.4.11,and avoid the version 10.4.11
