Denial of Service in uap-core when processing crafted User-Agent strings

Description

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.

Recommendation

Update the uap-core package to the latest compatible version. Followings are version details:

• Affected version(s): < 0.7.3
