tag_insight   = "mod_fcgid is a high performance alternative to mod_cgi or mod_cgid,
which starts a sufficient number instances of the CGI program to handle
concurrent requests, and these programs remain running to handle further
incoming requests. It is favored by the PHP developers, for example,
as a preferred alternative to running mod_php in-process, delivering
very similar performance.";
tag_solution  = "For the oldstable distribution (squeeze), this problem has been fixed in
version 1:2.3.6-1+squeeze2.

For the stable distribution (wheezy), this problem has been fixed in
version 1:2.3.6-1.2+deb7u1.

For the unstable distribution (sid), this problem has been fixed in
version 1:2.3.9-1.

We recommend that you upgrade your libapache2-mod-fcgid packages.";
tag_summary   = "Robert Matthews discovered that the Apache FCGID module, a FastCGI
implementation for Apache HTTP Server, fails to perform adequate
boundary checks on user-supplied input. This may allow a remote attacker
to cause a heap-based buffer overflow, resulting in a denial of service
or potentially allowing the execution of arbitrary code.";
