Gentoo Linux Security Advisory

Title: mod_fcgid: Multiple vulnerabilities (GLSA 201207-09)
Severity: high
Exploitable: local, remote
Date: July 09, 2012
Bug(s): #344685, #409373
ID: 201207-09

Synopsis

Multiple vulnerabilities have been found in mod_fcgid, allowing
execution of arbitrary code or Denial of Service.


Background

mod_fcgid is a binary-compatible alternative to mod_fastcgi with better
process management.


Affected Packages

Package: www-apache/mod_fcgid
Vulnerable: < 2.3.7
Unaffected: >= 2.3.7
Architectures: All supported architectures


Description

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.

Resolution

All mod_fcgid users should upgrade to the latest version:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=www-apache/mod_fcgid-2.3.7"
