Description Sachin Prabhu 2009-06-11 11:53:58 EDT
SoapClient :: __setSoapHeaders does not correctly set refcount for the header when there is only a single header object passed. Due to this, a later __soapCall() fails with a segmentation fault since the header has been freed due to its refcount being zero.

Reproducer built using sample from 

The script will not successfully run since the locations used in the sample script are all bogus. However this does demonstrate the problem clearly.

Required Result:

PHP Fatal error:  Uncaught SoapFault exception: [HTTP] Could not connect to host in /root/test.php:20
Stack trace:
#0 [internal function]: SoapClient->__doRequest('<?xml version="...', 'http://localhos...', 'http://test-uri...', 1, 0)
#1 /root/test.php(20): SoapClient->__soapCall('echoVoid', Array)
#2 /root/test.php(28): myclass->someOtherMethod()
#3 {main}
 thrown in /root/test.php on line 20

Actual Result:
Segmentation Fault

I've made test packages available which should fix this issue.  These
packages are unsupported, have not been through the standard Red Hat
QA process, and are not recommended for use on production systems.


Use of these packages may prevent you from (automatically) upgrading
to any asynchronous security errata which are issued before the
release of RHEL 5.5 due to version mismatches.

Please record any feedback on use of these test packages (positive or
negative!) on this bug report.
