"Stefan Eissing discovered that the HTTP/2 implementation in Apache did
not properly handle upgrade requests from HTTP/1.1 to HTTP/2 in some
situations. A remote attacker could use this to cause a denial of
service (daemon crash). This issue only affected Ubuntu 18.04 LTS and
Ubuntu 19.04. (CVE-2019-0197)

Craig Young discovered that a memory overwrite error existed in Apache
when performing HTTP/2 very early pushes in some situations. A remote
attacker could use this to cause a denial of service (daemon crash).
This issue only affected Ubuntu 18.04 LTS and Ubuntu 19.04.
(CVE-2019-10081)

Craig Young discovered that a read-after-free error existed in the
HTTP/2 implementation in Apache during connection shutdown. A remote
attacker could use this to possibly cause a denial of service (daemon
crash) or possibly expose sensitive information. This issue only
affected Ubuntu 18.04 LTS and Ubuntu 19.04. (CVE-2019-10082)

Matei Badanoiu discovered that the mod_proxy component of Apache did
not properly filter URLs when reporting errors in some configurations.
A remote attacker could possibly use this issue to conduct cross-site
scripting (XSS) attacks. (CVE-2019-10092)

Daniel McCarney discovered that mod_remoteip component of Apache
contained a stack buffer overflow when parsing headers from a trusted
intermediary proxy in some situations. A remote attacker controlling a
trusted proxy could use this to cause a denial of service or possibly
execute arbitrary code. This issue only affected Ubuntu 19.04.
(CVE-2019-10097)

Yukitsugu Sasaki discovered that the mod_rewrite component in Apache
was vulnerable to open redirects in some situations. A remote attacker
could use this to possibly expose sensitive information or bypass
intended restrictions. (CVE-2019-10098)

Jonathan Looney discovered that the HTTP/2 implementation in Apache
did not properly limit the amount of buffering for client connections
in some situations. A remote attacker could use this to cause a denial
of service (unresponsive daemon). This issue only affected Ubuntu
18.04 LTS and Ubuntu 19.04. (CVE-2019-9517).

description block directly from the Ubuntu security advisory. Tenable

"This update for apache2 fixes the following issues :

CVE-2019-0220: The Apache HTTP server did not use a consistent
strategy for URL normalization throughout all of its components. In
particular, consecutive slashes were not always collapsed. Attackers
could potentially abuse these inconsistencies to by-pass access
control mechanisms and thus gain unauthorized access to protected
parts of the service. [bsc#1131241]

CVE-2019-0217: A race condition in Apache's 'mod_auth_digest' when
running in a threaded server could have allowed users with valid
credentials to authenticate using another username, bypassing
configured access control restrictions. [bsc#1131239]

CVE-2019-0211: A flaw in the Apache HTTP Server allowed
less-privileged child processes or threads to execute arbitrary code
with the privileges of the parent process. Attackers with control over
CGI scripts or extension modules run by the server could have abused
this issue to potentially gain super user privileges. [bsc#1131233]

CVE-2019-0197: When HTTP/2 support was enabled in the Apache server
for a 'http' host or H2Upgrade was enabled for h2 on a 'https' host,
an Upgrade request from http/1.1 to http/2 that was not the first
request on a connection could lead to a misconfiguration and crash.
This issue could have been abused to mount a denial-of-service attack.
Servers that never enabled the h2 protocol or that only enabled it for
https: and did not configure the 'H2Upgrade on' are unaffected.
[bsc#1131245]

CVE-2019-0196: Through specially crafted network input the Apache's
http/2 request handler could be lead to access previously freed memory
while determining the method of a request. This resulted in the
request being misclassified and thus being processed incorrectly.

"This update for apache2 fixes the following issues :

CVE-2019-0211: A flaw in the Apache HTTP Server allowed
less-privileged child processes or threads to execute arbitrary code
with the privileges of the parent process. Attackers with control over
CGI scripts or extension modules run by the server could have abused
this issue to potentially gain super user privileges. [bsc#1131233]

CVE-2019-0220: The Apache HTTP server did not use a consistent
strategy for URL normalization throughout all of its components. In
particular, consecutive slashes were not always collapsed. Attackers
could potentially abuse these inconsistencies to by-pass access
control mechanisms and thus gain unauthorized access to protected
parts of the service. [bsc#1131241]

CVE-2019-0217: A race condition in Apache's 'mod_auth_digest' when
running in a threaded server could have allowed users with valid
credentials to authenticate using another username, bypassing
configured access control restrictions. [bsc#1131239]

CVE-2019-0197: When HTTP/2 support was enabled in the Apache server
for a 'http' host or H2Upgrade was enabled for h2 on a 'https' host,
an Upgrade request from http/1.1 to http/2 that was not the first
request on a connection could lead to a misconfiguration and crash.
This issue could have been abused to mount a denial-of-service attack.
Servers that never enabled the h2 protocol or that only enabled it for
https: and did not configure the 'H2Upgrade on' are unaffected.
[bsc#1131245]

CVE-2019-0196: Through specially crafted network input the Apache's
http/2 request handler could be lead to access previously freed memory
while determining the method of a request. This resulted in the
request being misclassified and thus being processed incorrectly.
[bsc#1131237]

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