Scientific Linux Security Update : httpd on SL7.x x86_64

Medium Nessus Plugin ID 85621


The remote Scientific Linux host is missing one or more security updates.


Multiple flaws were found in the way httpd parsed HTTP requests and responses using chunked transfer encoding. A remote attacker could use these flaws to create a specially crafted request, which httpd would decode differently from an HTTP proxy software in front of it, possibly leading to HTTP request smuggling attacks. (CVE-2015-3183)

It was discovered that in httpd 2.4, the internal API function ap_some_auth_required() could incorrectly indicate that a request was authenticated even when no authentication was used. An httpd module using this API function could consequently allow access that should have been denied. (CVE-2015-3185)

After installing the updated packages, the httpd service will be restarted automatically.


Update the affected packages.
