LDAP search segfaults when server returns error
Last modified: 2008-05-01 11:38:06 EDT
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; rv:1.7.3) Gecko/20041003 Firefox/0.10.1 Description of problem: Doing an LDAP search against one of our intranet LDAP servers results in a segmentation fault with Python 2.3.4 on Fedora Core 3. Here is a 2-line test case: server = ldap.initialize(URL) results = server.search_st(BASE, ldap.SCOPE_ONELEVEL, '(cn=anyone@gmail.com)', ['cn', 'email']) The gdb backtrace is attached. If I run the same code on a different system (Debian, Python 2.3.4, OpenLDAP 2.1.30), instead of a segfault I see an LDAP error: ldap.NO_RESULTS_RETURNED: {'info': '', 'desc': 'No results returned'} Based on the backtrace, I think the FC3 system is not handling that error correctly. Version-Release number of selected component (if applicable): python-ldap-2.0.1-2 How reproducible: Always Steps to Reproduce: 1. Run the 2-line test case above 2. Crash! 3. Additional info: Python version information: Python 2.3.4 (#1, Oct 26 2004, 16:42:40) [GCC 3.4.2 20041017 (Red Hat 3.4.2-6.fc3)] on linux2 Python and LDAP RPMs installed: python-2.3.4-11 nss_ldap-220-3 python-ldap-2.0.1-2 openldap-2.2.13-2 openldap-devel-2.2.13-2 openldap-clients-2.2.13-2 openldap-servers-2.2.13-2 cyrus-sasl-2.1.19-3 uname -a: Linux xxx.yyy.net 2.6.9-1.681_FC3.WKD_tr_mts_1 #1 Tue Nov 23 22:35:54 EST 2004 i686 athlon i386 GNU/Linux

Fedora Core 3 is now maintained by the Fedora Legacy project for security updates only. If this problem is a security issue, please reopen and reassign to the Fedora Legacy product. If it is not a security issue and hasn't been resolved in the current FC5 updates or in the FC6 test release, reopen and change the version to match. Thank you!
Closing per lack of response to previous request for information. This bug was originally filed against a much earlier version of Fedora Core, and significant changes have taken place since the last version for which this bug is confirmed. Note that FC3 and FC4 are supported by Fedora Legacy for security fixes only. Please install a still supported version and retest. If it still occurs on FC5 or FC6, please reopen and assign to the correct version. Otherwise, if this a security issue, please change the product to Fedora Legacy. Thanks, and we are sorry that we did not get to this bug earlier.
