- CVEs with nessus.description==Security Fix(es) :
- It was discovered that the HTTP parser in httpd
incorrectly allowed certain characters not permitted by
the HTTP protocol specification to appear unencoded in
HTTP request headers. If httpd was used in conjunction
with a proxy or backend server that interpreted those
characters differently, a remote attacker could possibly
use this flaw to inject data into HTTP responses,
resulting in proxy cache poisoning. (CVE-2016-8743)
Note: The fix for the CVE-2016-8743 issue causes httpd to return '400
Bad Request' error to HTTP clients which do not strictly follow HTTP
protocol specification. A newly introduced configuration directive
'HttpProtocolOptions Unsafe' can be used to re-enable the old less
strict parsing. However, such setting also re-introduces the
CVE-2016-8743 issue.
Note: Administrators of Red Hat Satellite 5 and Red Hat Satellite
Proxy 5 systems should consult Red Hat Knowledgebase article 3013361
linked to in the Reference section before installing this update.
Bug Fix(es) :
- Previously, httpd was unable to correctly check a
boundary of an array, and in rare cases it attempted to
access an element of an array that was out of bounds.
Consequently, httpd terminated unexpectedly with a
segmentation fault at proxy_util.c. With this update,
bounds checking has been fixed, and httpd no longer
crashes.
