Alpine: multiple squid packages: security update to 5.2-r0

high Tenable Self-Hosted Container Security Plugin ID 424555

Description

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

 - Squid through 4.14 and 5.x through 5.0.5, in some configurations, allows information disclosure because of
 an out-of-bounds read in WCCP protocol data. This can be leveraged as part of a chain for remote code
 execution as nobody. (CVE-2021-28116)

 - An issue was discovered in Squid 5.0.6 through 5.1.x before 5.2. When validating an origin server or peer
 certificate, Squid may incorrectly classify certain certificates as trusted. This problem allows a remote
 server to obtain security trust well improperly. This indication of trust may be passed along to clients,
 allowing access to unsafe or hijacked services. (CVE-2021-41611)
