"Several vulnerabilities have been found in the Apache HTTP server.

  - CVE-2018-17189
    Gal Goldshtein of F5 Networks discovered a denial of
    service vulnerability in mod_http2. By sending malformed
    requests, the http/2 stream for that request
    unnecessarily occupied a server thread cleaning up
    incoming data, resulting in denial of service.

  - CVE-2018-17199
    Diego Angulo from ImExHS discovered that
    mod_session_cookie does not respect expiry time.

  - CVE-2019-0196
    Craig Young discovered that the http/2 request handling
    in mod_http2 could be made to access freed memory in
    string comparison when determining the method of a
    request and thus process the request incorrectly.

  - CVE-2019-0211
    Charles Fol discovered a privilege escalation from the
    less-privileged child process to the parent process
    running as root.

  - CVE-2019-0217
    A race condition in mod_auth_digest when running in a
    threaded server could allow a user with valid
    credentials to authenticate using another username,
    bypassing configured access control restrictions. The
    issue was discovered by Simon Kappel.

  - CVE-2019-0220
    Bernhard Lorenz of Alpha Strike Labs GmbH reported that
    URL normalizations were inconsistently handled. When the
    path component of a request URL contains multiple
    consecutive slashes ('/'), directives such as
    LocationMatch and RewriteRule must account for
    duplicates in regular expressions while other aspects of
    the servers processing will implicitly collapse them."

CVE-2019-0217

A race condition in mod_auth_digest when running in a threaded server
could allow a user with valid credentials to authenticate using
another username, bypassing configured access control restrictions.
The issue was discovered by Simon Kappel.

CVE-2019-0220

Bernhard Lorenz of Alpha Strike Labs GmbH reported that URL
normalizations were inconsistently handled. When the path component of
a request URL contains multiple consecutive slashes ('/'), directives
such as LocationMatch and RewriteRule must account for duplicates in
regular expressions while other aspects of the servers processing will
implicitly collapse them.

For Debian 8 'Jessie', these problems have been fixed in version
2.4.10-10+deb8u14.

We recommend that you upgrade your apache2 packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
