Hi,

The following vulnerability was published for squid.

CVE-2023-50269[0]:
| Squid is a caching proxy for the Web. Due to an Uncontrolled
| Recursion bug in versions 2.6 through 2.7.STABLE9, versions 3.1
| through 5.9, and versions 6.0.1 through 6.5, Squid may be vulnerable
| to a Denial of Service attack against HTTP Request parsing. This
| problem allows a remote client to perform Denial of Service attack
| by sending a large X-Forwarded-For header when the
| follow_x_forwarded_for feature is configured. This bug is fixed by
| Squid version 6.6. In addition, patches addressing this problem for
| the stable releases can be found in Squid's patch archives.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
