Package : apache2
Version : 2.2.22-13+deb7u8
CVE ID : CVE-2016-8743
This upload fixes a security vulnerability in the header parsing code.
David Dennerline, of IBM Security's X-Force Researchers, and Régis
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
http://httpd.apache.org/docs/2.4/mod/core.html#httpprotocoloptions
For Debian 7 "Wheezy", these problems have been fixed in version
2.2.22-13+deb7u8.
We recommend that you upgrade your apache2 packages.
