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.

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)
