CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

A buffer overflow flaw in httpd's lua module could allow an out-of-bounds write. An attacker who is able to submit a crafted request to an httpd instance that is using the lua module may be able to cause an impact to confidentiality, integrity, and/or availability.

1 / 6

Remedy

Disabling mod_lua and restarting httpd will mitigate this flaw. See https://access.redhat.com/articles/10649 for more information.

Apache Tomcat could allow a remote attacker to execute arbitrary code on the system, caused by a file read/inclusion vulnerability in the AJP connector. By sending a specially-crafted request, an attacker could exploit this vulnerability to read web application files from a vulnerable server and upload malicious JavaServer Pages (JSP) code within a variety of file types and execute arbitrary code on the system.

Note: This vulnerability is known as Ghostcat.

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H

A read-after-free vulnerability was discovered in Apache httpd, in modhttp2. A specially crafted http/2 client session could cause the server to read memory that was previously freed during connection shutdown, potentially leading to a crash.

1 / 4

Remedy

This flaw is only exploitable if Apache httpd is configured to respond to HTTP/2 requests, which is done by including "h2" or "h2c" in the "Protocols" list in a configuration file. The following command can be used to search for possible vulnerable configurations: grep -R '^\s*Protocols\>.*\<h2\>' /etc/httpd/ See https://httpd.apache.org/docs/2.4/mod/mod_http2.html

Remedy

Unpatched servers can disable the h2/h2c protocol.

In Apache Batik 1.x before 1.10, when deserializing subclass of AbstractDocument, the class takes a string from the inputStream as the class name which then use it to call the no-arg constructor of the class. Fix was to check the class type before calling newInstance in deserialization.
