Package: apache2
Version: 2.0.52-3
Severity: important


we've reported this earlier and I thought that a php4 update fixed this
problem. Unfortunately, the bug reappeared this week again.

It seems that there is an environment corruption bug.

Minimal testcase:

Create a php file, umask.php, with:

------------------ snipp --------------------------
------------------ snipp --------------------------

Invoke w3m or another browser to open this file

create a cgi file, test.pl, with:

------------------ snipp --------------------------
#!/usr/bin/perl -w

print TMP "foobar\n\n";
close TMP;
------------------ snipp --------------------------

Request this cgi script a couple of times, e.g:

while true;do wget http://<hostname>/cgi-bin/test.pl;done

The output will look like this:
-rw-r--r--  1 www-data www-data     7 Dec 18 15:27 test.log.Sat Dec 18
15:27:50 CET 2004
-r------w-  1 www-data www-data     7 Dec 18 15:27 test.log.Sat Dec 18
15:27:51 CET 2004

The permissions on the second file are wrong. This behaviour causes all
sorts of funny side effects here. 

The cgi script is probably reusing the apache child environment of the
php script and therefore creates the file with wrong permissions.

We are using the debian testing php4 packages, 4.3.9.

I am not sure, if this is a bug in apache2 or in php4, though. So, feel
free to reassign, if necessary.

 php4 (4:4.3.10-3) unstable; urgency=medium
   * Update to CVS, as of 200502060530 (closes: #288672)
     - File uploads with "'" in them aren't cut off anymore (closes: #288679)
     - unserialize() is no longer ridiculously slow (closes: #291392)
     - Add 000-200502060530_CVS.patch
     - Adapt debian/rules to the realities of upstream's new buildconf
     - Add 033-we_WANT_libtool.patch, to force relibtoolizing with Debian's
       libtool, rather than using upstream's broken bundled libtool
     - Drop 031_zend_strtod_1.1.2.10.patch and 032_zend_strtod_debian.patch
     - Adjust patches for offsets and fuzz
     - Force --with-pic, as policy demands it, and the build system doesn't
   * Added several patches, yanked from the Fedora PHP sources:
     - 034-apache2_umask_fix.patch, fixes umask not being properly reset
       after each request (closes: #286225)
     - 036-fd_setsize_fix.patch, fixes misuse of FD_SET()
     - 038-round_test_fix.patch, makes the rounding test work on gcc-3.3
   * Removed --with-libedit, as being able to background php is more useful,
     in my opinion, than using readline functions (see #286356)
   * Include zip support in all SAPIs (closes: #288534, #288909)
   * Enable Zend Thread Safety for all SAPIs, meaning that our modules
     are now compiled for ZTS APIs as well.  (closes: #278212, #264015)
     - Make sure caudium-php4 now provides phpapi-$(ver), and modules can
       be configured with the caudium SAPI.
     - Add 039-reentrant_libs.patch to link to the reentrant versions of
       libldap and libmysqlclient
   * Stop suggesting phpdoc, as it's undistributable anyway.
   * Add 040-curl_open_basedir.patch, to make php4-curl respect the value
     of open_basedir, thanks to Martin Pitt (closes: #291410)
   * Add 041-shut_up_snmp.patch, to prevent libsnmp5 from attempting (and
     failing) to write persistent data every time it shuts down.  Ugh.
