Alpine: multiple squid packages: security update to 5.0.6-r0

high Tenable Self-Hosted Container Security Plugin ID 424527

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to a buffer-management bug, it
allows a denial of service. When resolving a request with the urn: scheme, the parser leaks a small amount
of memory. However, there is an unspecified attack methodology that can easily trigger a large amount of
memory consumption. (CVE-2021-28651)

- An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to incorrect parser validation, it
allows a Denial of Service attack against the Cache Manager API. This allows a trusted client to trigger
memory leaks that. over time, lead to a Denial of Service via an unspecified short query string. This
attack is limited to clients with Cache Manager API access privilege. (CVE-2021-28652)

- An issue was discovered in Squid 4.x before 4.15 and 5.x before 5.0.6. If a remote server sends a certain
response header over HTTP or HTTPS, there is a denial of service. This header can plausibly occur in
benign network traffic. (CVE-2021-28662)

- An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to a memory-management bug, it is
vulnerable to a Denial of Service attack (against all clients using the proxy) via HTTP Range request
processing. (CVE-2021-31806)
