Title
PCRE ‘match’函数信息泄露漏洞
Description
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 8.37之前版本的pcre_exec.c文件中的‘match’函数存在安全漏洞，该漏洞源于程序未能正确处理‘/(?:((abcd))|(((?:(?:(?:(?:abc|(?:abcdef))))b)abcdefghi)abc)|((*ACCEPT)))/’模式和涉及(*ACCEPT)的相关模式。远程攻击者可借助特制的正则表达式利用该漏洞获取进程内存中的敏感信息，或造成拒绝服务（部分内存未初始化和应用程序崩溃）。
