https://bugs.openldap.org/show_bug.cgi?id=10218 Issue ID: 10218 Summary: Disabling and re-enabling an asyncmeta database via cn=config leaks memory Product: OpenLDAP Version: 2.6.7 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: backends Assignee: bugs(a)openldap.org Reporter: nivanova(a)symas.com Target Milestone: --- To reproduce - run OpenLDAP with valgrind, and set the olcDisabled attribute of an asyncmeta database to TRUE, then again to FALSE. The connection structures of the database are subsequently shown as leaked. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10217] New: autoca should support more key types

https://bugs.openldap.org/show_bug.cgi?id=10217 Issue ID: 10217 Summary: autoca should support more key types Product: OpenLDAP Version: 2.6.7 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: enhancement Priority: --- Component: overlays Assignee: bugs(a)openldap.org Reporter: hyc(a)openldap.org Target Milestone: --- Currently autoca only creates certificates using RSA keypairs. It should at least have an option to use Elliptic Curve keypairs. It probably also needs options to specify other signature algorithms other than the default of SHA256. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10212] New: read-only tools may use wrong meta page

https://bugs.openldap.org/show_bug.cgi?id=10212 Issue ID: 10212 Summary: read-only tools may use wrong meta page Product: LMDB Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: hyc(a)openldap.org Target Milestone: --- On a quiescent database that's only used for read-only txns, the txnid won't be initialized so it remains set to zero. Then only meta page zero will get used, even if page one is newer. Thus all information retrieved will be stale by one txn. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10216] New: Channel binding enforced on AD with AD cert using EDCSA-SHA384 fails

https://bugs.openldap.org/show_bug.cgi?id=10216 Issue ID: 10216 Summary: Channel binding enforced on AD with AD cert using EDCSA-SHA384 fails Product: OpenLDAP Version: 2.6.7 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: libraries Assignee: bugs(a)openldap.org Reporter: simon.pichugin(a)gmail.com Target Milestone: --- Secure LDAP connections to the target Windows server 2019 DC began failing after the Windows Server DC certificate was updated to an Elliptic Curve Public Key (384 bits) with the sha384ECDSA signature algorithm and sha384 signature hash algorithm specified. The connections were previously successful when the Windows server DC certificate specified an RSA Public Key certificate with signature algorithm sha256RSA and signature hash algorithm sha256 specified. Once the Windows server domain controller certificate is upgraded to the ECC public key, subsequent secure ldap connection attempts fail. If channel binding is turned off on the Windows AD target server, secure ldap connections will succeed using starttls. If Windows server domain controller certificate is upgraded to ECC public key and ldap channel binding is enforced, subsequent secure ldap connection attempts fail with this error message: ldap_sasl_interactive_bind_s: Invalid credentials (49) additional info: 80090346: LdapErr: DSID-0C09070F, comment: AcceptSecurityContext error, data 80090346, v4563 Expected results: Kerberos SASL should work with STARTTLS even when AD certificate is ECC and SASL_CBINDING is set to "tls-endpoint" Actual results: Kerberos SASL only works with STARTTLS even when AD certificate is RSA and SASL_CBINDING is set to "tls-endpoint"; it fails when AD certificate is ECC Additional information: According to the OpenSSL maintainer, there might be a bug in the OpenLDAP code: it uses EVP_get_digestbynid() to find a digest algorithm based on the signature algorithm, but there might be no such mapping in EC compared to the RSA case. OpenLDAP needs to use OBJ_find_sigid_algs() to find the right algorithm. Possibly, this is the failing code: https://git.openldap.org/openldap/openldap/-/blob/master/libraries/libldap/… Instead of X509_get_signature_nid() OpenLDAP code probably should call something like OBJ_find_sigid_algs(X509_get_signature_nid(cert), &md_nid, &pk_nid). The former only supports mapping for a few known signature algorithms, but everything did work, most likely due to a fallback to sha256 in case the digest wasn't really found. Judging by https://github.com/openssl/openssl/issues/14278 and https://github.com/openssl/openssl/issues/14467, a better API is coming but not currently available (and as it was in the state for a few years, it probably won't be coming soon) -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10214] New: Reduce library dependencies

https://bugs.openldap.org/show_bug.cgi?id=10214 Issue ID: 10214 Summary: Reduce library dependencies Product: OpenLDAP Version: unspecified Hardware: All OS: Linux Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: hamano(a)osstech.co.jp Target Milestone: --- Currently, slapd links libsystemd to notify service state to systemd. However, libsystemd link several unnecessary libraries, which increases security risks. The systemd documentation provides a method to send state notifications to systemd using a simple protocol without the need to link against libsystemd. https://www.freedesktop.org/software/systemd/man/devel/sd_notify.html I propose removing libsystemd and its depended libraries, similar to the approach taken by OpenSSH. Applying this fix reduced the following ten dependencies in the RHEL 8 environment. - libsystemd.so.0 - libblkid.so.1 - libcap.so.2 - libgcc_s.so.1 - libgcrypt.so.20 - libgpg-error.so.0 - liblz4.so.1 - liblzma.so.5 - libmount.so.1 - librt.so.1 -- You are receiving this mail because: You are on the CC list for the issue.

Is there any ldap module that uses the openssl library of the SO that in this case its the openssl 1.1.1f to hash its passwords?, could be this https://github.com/openldap/openldap/tree/master/contrib/slapd-modules/pass… maybe if i'm understanding right? thx! -- You are receiving this mail because: You are on the CC list for the issue.
