Debian DLA-1748-1 : apache2 security update

high Nessus Plugin ID 123689

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Several vulnerabilities have been found in the Apache HTTP server.

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.

Solution

Upgrade the affected packages.
