Spring Framework DoS via conditional HTTP request
### Description
Applications that parse ETags from `If-Match` or `If-None-Match` request headers are vulnerable to DoS attack.

### Affected Spring Products and Versions
org.springframework:spring-web in versions 

6.1.0 through 6.1.11
6.0.0 through 6.0.22
5.3.0 through 5.3.37

Older, unsupported versions are also affected

### Mitigation
Users of affected versions should upgrade to the corresponding fixed version.
6.1.x -> 6.1.12
6.0.x -> 6.0.23
5.3.x -> 5.3.38
No other mitigation steps are necessary.

Users of older, unsupported versions could enforce a size limit on `If-Match` and `If-None-Match` headers, e.g. through a Filter.

Spring Framework URL Parsing with Host Validation
Applications that use UriComponentsBuilder to parse an externally provided URL (e.g. through a query parameter) AND perform validation checks on the host of the parsed URL may be vulnerable to a  open redirect https://cwe.mitre.org/data/definitions/601.html  attack or to a SSRF attack if the URL is used after passing validation checks.

This is the same as  CVE-2024-22259 https://spring.io/security/cve-2024-22259  and  CVE-2024-22243 https://spring.io/security/cve-2024-22243 , but with different input.
