https://bugs.openldap.org/show_bug.cgi?id=9711 Issue ID: 9711 Summary: olcTLSVerifyClient set incorrectly on conversion Product: OpenLDAP Version: 2.5.7 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: quanah(a)openldap.org Target Milestone: --- When converting the following slapd.conf to cn=config via slaptest, the olcTLSVerifyClient parameter is set to "demand" instead of "never". The slapd.conf man page clearly states that "never" is supposed to be the default. This causes startTLS operations to fail from the client. slapd.conf: include /opt/symas/etc/openldap/schema/core.schema pidfile /var/symas/run/slapd.pid argsfile /var/symas/run/slapd.args loglevel stats TLSCACertificateFile /opt/symas/ssl/CA/certs/testsuiteCA.crt TLSCertificateFile /opt/symas/ssl/certs/ub18.crt TLSCertificateKeyFile /opt/symas/ssl/private/ub18.key modulepath /opt/symas/lib/openldap moduleload back_mdb.la database config rootpw secret database mdb maxsize 1073741824 suffix "dc=my-domain,dc=com" rootdn "cn=Manager,dc=my-domain,dc=com" rootpw secret directory /var/symas/openldap-data index objectClass eq database monitor With the above slapd.conf, the following ldapsearch command succeeds: /opt/symas/bin/ldapsearch -x -ZZ -H ldap://ub18.quanah.org/^ However, after converting it to cn=config: slaptest -f slapd.conf -F /opt/symas/etc/openldap/slapd.d olcTLSVerifyClient has an incorrect value of "demand" instead of "never": cn=config.ldif:olcTLSVerifyClient: demand -- You are receiving this mail because: You are on the CC list for the issue.

However, if change the case in (container ⇒ Container): olcSuffix: cn=krbContainer no matter how I set olcAccess in the frontend database, $ ldapsearch -xb "" -s base namingContexts always prints dn: namingContexts: cn=krbContainer In particular olcAccess: to dn.base="" attrs=namingContexts val/distinguishedNameMatch="cn=krbcontainer" by * none does not hide it. • It shall be possible to find olcSuffix from the DSE/namingContexts, even if the suffix is mixCased. Since the case is known at the time, when the rules are written, OpenLDAP shall offer an option for exact match, without converting data to lowercase.

[Issue 9696] New: OpenSSL implementation of LDAP_OPT_X_TLS_PEERCERT leaks memory
by openldap-its＠openldap.org 11 Oct '21

https://bugs.openldap.org/show_bug.cgi?id=9696 Issue ID: 9696 Summary: OpenSSL implementation of LDAP_OPT_X_TLS_PEERCERT leaks memory Product: OpenLDAP Version: 2.4.57 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: libraries Assignee: bugs(a)openldap.org Reporter: cheimes(a)redhat.com Target Milestone: --- The OpenSSL implementation of ldap_get_option() LDAP_OPT_X_TLS_PEERCERT leaks memory. The internal function tlso_session_peercert() uses SSL_get_peer_certificate() to access the server certificate. SSL_get_peer_certificate() increases the reference counter of the peer cert by one. The code is missing a X509_free() call to decref the internal reference counter by one. I also recommend that you check the return value of SSL_get_peer_certificate() for NULL. There are cases when a TLS session does not have access to a peer certificate, e.g. session resumption.

[Issue 9668] New: undefined behavior for isdigit in tls2.c

Depending on the platform, the process may crash or wrongly classify the host name as either numeric or non-numeric. While here, I noticed that both sni and c have type 'char *', but they should rather be 'const char *'. Was there a specific reason to suggest to the reader the host name would be modifiable? -- You are receiving this mail because: You are on the CC list for the issue.
