New! Plugin Severity Now Using CVSS v3

Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for apache2 fixes the following issues :

Security issues fixed :

CVE-2018-17199: A bug in Apache's 'mod_session_cookie' lead to an issue where the module did not respect a cookie's expiry time.
[bsc#1122839]

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]

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.

Solution

To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or 'zypper patch'.
