www/squid4: update to 4.13

Update squid4 to 4.13 (Squid 4.13).

Here is release announce:

The Squid HTTP Proxy team is very pleased to announce the availability
of the Squid-4.13 release!


This release is a security release resolving several issues found in
the prior Squid releases.


The major changes to be aware of:

 * SQUID-2020:8 HTTP(S) Request Splitting
   (CVE-2020-15811)

This problem is serious because it allows any client, including
browser scripts, to bypass local security and poison the browser
cache and any downstream caches with content from an arbitrary
source.

See the advisory for patches:
 <https://github.com/squid-cache/squid/security/advisories/GHSA-c7p8-xqhm-49wv>


 * SQUID-2020:9 Denial of Service processing Cache Digest Response
   (CVE pending allocation)

This problem allows a trusted peer to deliver to perform Denial
of Service by consuming all available CPU cycles on the machine
running Squid when handling a crafted Cache Digest response
message.

This attack is limited to Squid using cache_peer with cache
digests feature.

See the advisory for patches:
 <https://github.com/squid-cache/squid/security/advisories/GHSA-vvj7-xjgq-g2jg>


 * SQUID-2020:10 HTTP(S) Request Smuggling
   (CVE-2020-15810)

This problem is serious because it allows any client, including
browser scripts, to bypass local security and poison the proxy
cache and any downstream caches with content from an arbitrary
source.


See the advisory for patches:
 <https://github.com/squid-cache/squid/security/advisories/GHSA-3365-q9qx-f98m>


 * Bug 5051: Some collapsed revalidation responses never expire

This bug appears as a 4xx or 5xx status response becoming the only
response delivered by Squid to a URL when Collapsed Forwarding
feature is used.

It primarily affects Squid which are caching the 4xx/5xx status
object since Bug 5030 fix in Squid-4.11. But may have been
occurring for short times on any proxy with Collapsed Forwarding.



 * SSL-Bump: Support parsing GREASEd (and future) TLS handshakes

Chrome Browser intentionally sends random garbage values in the
TLS handshake to force TLS implementations to cope with future TLS
extensions cleanly. The changes in Squid-4.12 to disable TLS/1.3
caused our parser to be extra strict and reject this TLS garbage.

This release adds explicit support for Chrome, or any other TLS
agent performing these "GREASE" behaviours.


 * Honor on_unsupported_protocol for intercepted https_port

This behaviour was one of the intended use-cases for unsupported
protocol handling, but somehow was not enabled earlier.

Squid should now be able to perform the on_unsupported_protocol
selected action for any traffic handled by SSL-Bump.


  All users of Squid are urged to upgrade as soon as possible.


See the ChangeLog for the full list of changes in this and earlier
releases.
