Scientific Linux Security Update : httpd on SL5.x, SL6.x i386/x86_64 (httpoxy)
Medium Nessus Plugin ID 92403
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionSecurity Fix(es) :
- It was discovered that httpd used the value of the Proxy header from HTTP requests to initialize the HTTP_PROXY environment variable for CGI scripts, which in turn was incorrectly used by certain HTTP client implementations to configure the proxy for outgoing HTTP requests. A remote attacker could possibly use this flaw to redirect HTTP requests performed by a CGI script to an attacker-controlled proxy via a malicious HTTP request.
Note: After this update, httpd will no longer pass the value of the Proxy request header to scripts via the HTTP_PROXY environment variable.
SolutionUpdate the affected packages.
