high Nessus Plugin ID 124125

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

In Apache HTTP Server with MPM event, worker or prefork, code executing in less-privileged child processes or threads (including scripts executed by an in-process scripting interpreter) could execute arbitrary code with the privileges of the parent process (usually root) by manipulating the scoreboard. (CVE-2019-0211)

mod_http2: read-after-free on a string compare (CVE-2019-0196)

mod_http2: possible crash on late upgrade (CVE-2019-0197)

httpd: URL normalization inconsistency (CVE-2019-0220)

In Apache HTTP Server 2.4 releases 2.4.37 and 2.4.38, a bug in mod_ssl when using per-location client certificate verification with TLSv1.3 allowed a client to bypass configured access control restrictions.(CVE-2019-0215)

A race condition was found in mod_auth_digest when the web server was running in a threaded MPM configuration. It could allow a user with valid credentials to authenticate using another username, bypassing configured access control restrictions.(CVE-2019-0217)

Solution

Run 'yum update httpd' to update your system.
