"The remote host is affected by the vulnerability described in GLSA-201207-09
(mod_fcgid: Multiple vulnerabilities)

    Multiple vulnerabilities have been found in mod_fcgid:
      An error in the 'fcgid_header_bucket_read()' function in
        fcgid_bucket.c could cause a stack-based buffer overflow
        (CVE-2010-3872).
      An error in the 'is_spawn_allowed() function in fcgid_spawn_ctl.c
        prevents Apache from recognizing the FcgidMaxProcessesPerClass
        directive for a virtual host (CVE-2012-1181).
  
Impact :

    A local attacker could possibly execute arbitrary code with the
      privileges of the process or cause a Denial of Service condition.
      Furthermore, a remote attacker could send specially crafted HTTP
      requests, possibly resulting in a Denial of Service condition.
  
Workaround :

    There is no known workaround at this time."
