Summary

OpenLDAP 1.0 through 2.1.19, as used in Apple Mac OS 10.3.4 and 10.3.5 and possibly other operating systems, may allow certain authentication schemes to use hashed (crypt) passwords in the userPassword attribute as if they were plaintext passwords, which allows remote attackers to re-use hashed passwords without decrypting them.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
