Affected Packages:
Security database references:
In Mitre's CVE dictionary: CVE-2019-0217, CVE-2019-0220.
More information:

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.
