CVE Request: PCRE Library Stack Overflow Vulnerability

["wen_guanxing" <wen_guanxing () venustech com cn>]

Hello,


PCRE is a regular expression C library inspired by the regular expression capabilities in the Perl programming 
language. The PCRE library is incorporated into a number of prominent programs, such as the Adobe Flash, Apache, Nginx 
and PHP. 


PCRE library is prone to a vulnerability which leads to Stack Overflow. Without enough bound checking inside 
compile_regex(), the stack memory could be overflowed via a crafted regular expression. Since PCRE library is widely 
used, this vulnerability should affect many applications. An attacker may exploit this issue to execute arbitrary code 
in the context of the user running the affected application.
