|Gentoo Linux Security Advisory
Title: mod_fcgid: Multiple vulnerabilities (GLSA 201207-09)
Exploitable: local, remote
Date: July 09, 2012
Bug(s): #344685, #409373
Multiple vulnerabilities have been found in mod_fcgid, allowing
execution of arbitrary code or Denial of Service.
mod_fcgid is a binary-compatible alternative to mod_fastcgi with better
Vulnerable: < 2.3.7
Unaffected: >= 2.3.7
Architectures: All supported architectures
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
- 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).
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.
There is no known workaround at this time.
All mod_fcgid users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apache/mod_fcgid-2.3.7"
