  script_tag(name:"insight", value:"This upload fixes a security vulnerability in the header parsing code.

David Dennerline, of IBM Security's X-Force Researchers, and Regis Leroy discovered problems in the way Apache handled a broad pattern of unusual whitespace patterns in HTTP requests. In some configurations, this could lead to response splitting or cache pollution vulnerabilities. To fix these issues, this update makes Apache httpd be more strict in what HTTP requests it accepts.

If this causes problems with non-conforming clients, some checks can be relaxed by adding the new directive HttpProtocolOptions unsafe to the configuration. More information is available at


For Debian 7 Wheezy, these problems have been fixed in version 2.2.22-13+deb7u8.

We recommend that you upgrade your apache2 packages.
