Filehandles of logs not closed before exec of cgi scripts
Summary: Filehandles of logs not closed before exec of cgi
scripts
Product: Apache httpd-2.0
Version: 2.0.44
Platform: All
OS/Version: FreeBSD
Status: NEW
Severity: Critical
Priority: Other
Component: Core
AssignedTo: bugs@httpd.apache.org
ReportedBy: ck@cksoft.de
We updated one of our servers from apache-2.0.39 to
apache-2.0.44 and noticed that 2.0.44 fails to close
the file handles of the logfiles before executing cgi
scripts.
We test by running a php script via the cgi interface and
using lsof to list the open file handles. (See below)
This enables cgi's to access the logs of other virtual hosts.
We can reproduce this under FreeBSD 4-STBALE and 5.0 RELEASE
using the preforked mpm and apache-2.0.40, 2.0.43 and 2.0.44.
The problem does not occur on apache-2.0.39.
We think this bug might be related to Bug 12774 which was closed
due to lack of response from the original poster. This was also
oing from 2.0.39 to 2.0.40.
This could also be related to the changes in apr/file_io/src/unix/file_dup.c
from 1.48 to 1.49 and the introduction of apr_file_setaside().
These changes were after 2.0.39 and before 2.0.40.
