Details

USN-3937-1 and USN-3627-1 fixed several vulnerabilities in Apache.
This update provides the corresponding update for Ubuntu 12.04 ESM.

Original advisory details:

Simon Kappel discovered that the Apache HTTP Server mod_auth_digest module
incorrectly handled threads. A remote attacker with valid credentials could
possibly use this issue to authenticate using another username, bypassing
access control restrictions. (CVE-2019-0217)

Alex Nichols and Jakob Hirsch discovered that the Apache HTTP Server mod_authnz_ldap
module incorrectly handled missing charset encoding headers. A remote attacker
could possibly use this issue to cause the server to crash, resulting in a denial of
service. (CVE-2017-15710)

Robert Swiecki discovered that the Apache HTTP Server incorrectly handled
certain requests. A remote attacker could possibly use this issue to cause
the server to crash, leading to a denial of service. (CVE-2018-1301)

Nicolas Daniels discovered that the Apache HTTP Server incorrectly generated
the nonce when creating HTTP Digest authentication challenges. A remote attacker
could possibly use this issue to replay HTTP requests across a cluster of servers.
(CVE-2018-1312)
