Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities have been found in mod_fcgid, allowing |
| 19 |
execution of arbitrary code or Denial of Service. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
mod_fcgid is a binary-compatible alternative to mod_fastcgi with better |
| 25 |
process management. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 www-apache/mod_fcgid < 2.3.7 >= 2.3.7 |
| 34 |
|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Multiple vulnerabilities have been found in mod_fcgid: |
| 39 |
|
| 40 |
* An error in the "fcgid_header_bucket_read()" function in |
| 41 |
fcgid_bucket.c could cause a stack-based buffer overflow |
| 42 |
(CVE-2010-3872). |
| 43 |
* An error in the "is_spawn_allowed() function in fcgid_spawn_ctl.c |
| 44 |
prevents Apache from recognizing the FcgidMaxProcessesPerClass |
| 45 |
directive for a virtual host (CVE-2012-1181). |
| 46 |
|
| 47 |
Impact |
| 48 |
====== |
| 49 |
|
| 50 |
A local attacker could possibly execute arbitrary code with the |
| 51 |
privileges of the process or cause a Denial of Service condition. |
| 52 |
Furthermore, a remote attacker could send specially crafted HTTP |
| 53 |
requests, possibly resulting in a Denial of Service condition. |
| 54 |
|
| 55 |
Workaround |
| 56 |
========== |
| 57 |
|
| 58 |
There is no known workaround at this time. |
| 59 |
|
| 60 |
Resolution |
| 61 |
========== |
| 62 |
|
| 63 |
All mod_fcgid users should upgrade to the latest version: |
| 64 |
|
| 65 |
# emerge --sync |
| 66 |
# emerge --ask --oneshot --verbose ">=www-apache/mod_fcgid-2.3.7" |
| 67 |
|
