New Comment:
So perhaps keep user id (getuid()) in the cache filename?

Even one SAPI in shared environment will have the same issue.
If you have several php-cgi processes with different UID, only one of
them will own the cache file, and all others won't be able to access it.

Do you mean different SAPI's like CLI?
But different SAPI's have separate php.ini file, where they can
define path suitable for them (writable).
And in fact i've done that in our distribution. So you consider this
distribution related issue?

I am not sure it is a good patch.
The same WSDL files may be used by different users and your patch will
allow access to cache only to first user.

Description:
soap cache file is created with insecure permissions on some
configurations:
-rw-rw-rw- 1 http http 67K Oct 12 19:10
wsdl-cf39a31ae8dbd9b9899539495756434d
by default cache is enabled and cache directory is set to /tmp:
http://ee.php.net/manual/en/ref.soap.php
#ifdef ZEND_WIN32
f = open(fn,O_CREAT|O_WRONLY|O_EXCL|O_BINARY,S_IREAD|S_IWRITE);
#else
f = open(fn,O_CREAT|O_WRONLY|O_EXCL|O_BINARY,S_IREAD|S_IWRITE|
S_IROTH|S_IWOTH|S_IRGRP|S_IWGRP);
#endif
probably in shared enviroments somebody could replace cache file
with evil content and cause soap requests to be sent to infectected
webserver capturing user passwords logins, depending on application.
Reproduce code:
---
create sample wsdl.xml from:
http://www.roguewave.com/support/docs/leif/leif/html/soapworxug/A-1.html
$ (rm -f /tmp/wsdl-*; umask 0; strace -ff -eopen php -r '$s = new
SoapClient(/tmp/wsdl.xml);' 21|grep wsdl; ls -l /tmp/wsdl-*)
open(/tmp/wsdl-d3d4b363f5423ee77d7e0342af8881c7, O_RDONLY) = -1
ENOENT (No such file or directory)
open(/tmp/wsdl.xml, O_RDONLY) = 5
open(/tmp/wsdl-d3d4b363f5423ee77d7e0342af8881c7,
O_WRONLY|O_CREAT|O_EXCL, 0666) = 5
