Vulnerability Title
PHP Filter_Var函数FILTER_VALIDATE_EMAIL注入换行漏洞
Vulnerability Description
PHP是广泛使用的通用目的脚本语言，特别适合于Web开发，可嵌入到HTML中。 PHP的ext/filter扩展在使用正则表达式库时存在漏洞，远程攻击者可能利用此漏洞输入恶意邮件。 PHP的ext/filter扩展内部对正则表达式使用了PCRE库。在FILTER_VALIDATE_EMAIL过滤器中没有使用"D"修饰符，而如果PCRE正则表达式中没有使用"D"修饰符的话，"$"的意思就不是"标题的末尾"，而是"标题的末尾或接近带有单个换行符的末尾"，这样恶意用户就可以在邮件头中注入换行符。
