Full_Name: Raymond Edah Version: JLDAP CVS HEAD OS: Windows URL: http://www.cs.skyblue.eu.com/ray/code/LDAPPasswordPolicyResponse.tar.gz Submission from: (NULL) (81.3.106.202) Hi, I have written a class for handling the password policy response control as described in draft-behera-ldap-password-policy-09.txt. I would like to contribute it to the OpenLDAP project. A copy of the code can be found at http://www.cs.skyblue.eu.com/ray/code/LDAPPasswordPolicyResponse.tar.gz. Regards, Ray Edah

(ITS#5388) NULL pointer dereference
by dhen42＠yahoo.co.uk 25 Feb '08

25 Feb '08

Full_Name: Dennis Henriksen Version: 2.4.8 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (194.237.142.10) In server/slapd/oc.c(oc_next) suffers from a potential NULL pointer dereference in the statement '*oc = LDAP_STAILQ_NEXT(*oc,soc_next);'. Perhaps this should read (if *oc != NULL) *oc = LDAP_STAILQ_NEXT(*oc,soc_next);'

I may have misunderstood, but it seems this concerns internal errors, whereas I was referring to the output (writing the data to stdout or to a file) errors. The patch I attached addresses this issue, is there any chance of seeing it included in OpenLDAP, or does it need some more work?

API design bug. ldif_tool_entry_first()/ldif_tool_entry_next() have no way to return error. At best they can set an "error" flag in the internal database structure, and API calls which are able to return errors can react to that. -- Hallvard

(ITS#5387) slapcat ignores errors while writing output (no space left on device, etc)

Full_Name: Jonathan Clarke Version: 2.3, HEAD OS: Linux URL: ftp://ftp.openldap.org/incoming/jonathan-clarke-20080220.patch.3 Submission from: (NULL) (213.41.243.192) Hi all, When slapcat is writing it's output to disk, it ignores any errors (with slapcat -l output_file or slapcat > output_file). If an error is encountered, such as "No space left on device", slapcat then exits normally with a return code of 0. This seems pretty dangerous to me - if you back up your database with slapcat, but don't get an error on failure, it could easily lead to data loss. Please find at the address below a patch to stop on such errors. It may require some cleaning up - apologies if so. Regards, Jonathan

In this case users of web2ldap could work around it by using a locally stored schema LDIF file for back-config. Ciao, Michael.

I note that there's no such problem with RE24. If we can't track this down easily I'm inclined to just ignore it. -- -- Howard Chu Chief Architect, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

(ITS#5386) Bad value of entryUUID in filter crashes slapd
by silk＠boktor.net 18 Feb '08

Full_Name: Grzegorz Sobanski Version: 2.4.7(-5) OS: Debain unstable URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (150.254.130.134) If client sends a filter that lookups entries based on entryUUID, and the value of entryUUID is invalid (eg. not properly formed) slapd dies with an assertion. Example filter: (entryUUID=baka) Steps to reproduce: ldapsearch -x "(entryUUID=baka)" Reproducible: always Error logged by slapd: slapd: /home/devel/openldap/build-area/openldap2.3-2.4.7/servers/slapd/schema_init.c:2537: UUIDNormalize: Assertion `val->bv_len == 16' failed. Expected behaviour: Server does not dies, and: - backwards compatible: filter on entryUUID is skipped - not backward compatible: client is informed about malformed search filter If any more information or tests are needed, please ask.
