Hope you all are doing well.

There is a Vulnerability reported on Boost library as mentioned below.  Any guidance or assistance or reply to this mail would be greatly appreciated.

Vulnerability ID: BDSA-2018-2656
Vulnerability Details:
          Boost has a flaw in the function boost::re_detail_NUMBER::basic_regex_creator which can lead to a buffer over-read. An attacker can craft and send a malicious file which will trigger the buffer over-read, leading to a denial-of-service.

Few query w.r.t boost::re_detail_NUMBER::basic_regex_creator() function:

1. Does Boost.Regex library or any Boost library internally use this function?
2. If the answer is yes, Which all libraries use this function?
3. Is this a known vulnerability and is it fixed in the latest Boost version? please provide some insights like (any change list or file name etc).

Our project uses a boost library(which has file "boost/regex/v4/basic_regex_creator.hpp") and uses Boost.Regex library functions. Should we be worried about this vulnerability (BDSA-2018-2656) affecting our code? 

Thanks!
