Several security issues were fixed in Squid.

Jeriko One and Kristoffer Danielsson discovered that Squid incorrectly
handled certain URN requests. A remote attacker could possibly use this
issue to bypass access checks and access restricted servers. This issue was
only addressed in Ubuntu 19.04 and Ubuntu 19.10. (CVE-2019-12523)

Jeriko One discovered that Squid incorrectly handed URN responses. A remote
attacker could use this issue to cause Squid to crash, resulting in a
denial of service, or possibly execute arbitrary code. (CVE-2019-12526)

Alex Rousskov discovered that Squid incorrectly handled certain strings. A
remote attacker could possibly use this issue to cause Squid to crash,
resulting in a denial of service. This issue only affected Ubuntu 19.04.
(CVE-2019-12854)

Jeriko One and Kristoffer Danielsson discovered that Squid incorrectly
handled certain input. A remote attacker could use this issue to cause
Squid to crash, resulting in a denial of service, or possibly execute
arbitrary code. This issue was only addressed in Ubuntu 19.04 and Ubuntu
19.10. (CVE-2019-18676)

Kristoffer Danielsson discovered that Squid incorrectly handled certain
messages. This issue could result in traffic being redirected to origins
it should not be delivered to. (CVE-2019-18677)

Régis Leroy discovered that Squid incorrectly handled certain HTTP
request headers. A remote attacker could use this to smuggle HTTP requests
and corrupt caches with arbitrary content. (CVE-2019-18678)

David Fifield discovered that Squid incorrectly handled HTTP Digest
Authentication. A remote attacker could possibly use this issue to obtain
pointer contents and bypass ASLR protections. (CVE-2019-18679)
