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
