Denial of Service in uap-core

Impact

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.

Patches

Please update uap-core to >= v0.11.0

Downstream packages such as uap-python, uap-ruby etc which depend upon uap-core follow different version schemes.
