Detailsinfo

A vulnerability was found in OpenLDAP (Directory Service Software). It has been declared as problematic. Affected by this vulnerability is an unknown code in the library libraries/libldap/tls_m.c of the component Libraries. The manipulation with an unknown input leads to a information disclosure vulnerability. The CWE definition for the vulnerability is CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. As an impact it is known to affect confidentiality. The summary by CVE is:

libraries/libldap/tls_m.c in OpenLDAP, possibly 2.4.31 and earlier, when using the Mozilla NSS backend, always uses the default cipher suite even when TLSCipherSuite is set, which might cause OpenLDAP to use weaker ciphers than intended and make it easier for remote attackers to obtain sensitive information.

The weakness was shared 06/16/2012 as Bug 825875 as confirmed bug report (Bugzilla). The advisory is shared at bugzilla.redhat.com. This vulnerability is known as CVE-2012-2668 since 05/14/2012.
