SCA: security update for uap-core (GHSA-p4pj-mg4r-x6v4)

medium Tenable Cloud Security Plugin ID 417278

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - uap-core in an open-source npm package which contains the core of BrowserScope's original user agent
 string parser. In uap-core before version 0.11.0, some regexes are vulnerable to regular expression denial
 of service (REDoS) due to overlapping capture groups. This allows remote attackers to overload a server by
 setting the User-Agent header in an HTTP(S) request to maliciously crafted long strings. This is fixed in
 version 0.11.0. Downstream packages such as uap-python, uap-ruby etc which depend upon uap-core follow
 different version schemes. (CVE-2021-21317)
