Severity:high
Title:mod_fcgid: Multiple vulnerabilities
Date:07/09/2012
Bugs: #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 Vulnerable Unaffected Architecture(s)
www-apache/mod_fcgid < 2.3.7 >= 2.3.7 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:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=www-apache/mod_fcgid-2.3.7"
